Rubio, the son of Cuban immigrants, is a senator from Florida. He previously served as a legislator in the state of Florida. His energy plan has been praised by Oklahoma State Senator David Holt. (Here are the remarks he posted from his trip to Oklahoma City on September 2, 2015.) Despite this, his energy plan does not have a solution for a state which is suffering due to low oil prices worldwide.
Some of his other policy areas include a paid leave system, which offers companies a tax credit for offering four to twelve weeks of paid leave, a typical conservative stance towards guns, support for the expansion of Section 215 of the Patriot Act, which is used to collect records, and foreign policy views that emphasize American strength vs. Evil Empires, which was a worldview condemned by President Obama during his 2016 State of the Union address. Rubio also supports a merit-based immigration system.

The Atlantic covered his performance in a January 2016 presidential debate.

Next is Ben Carson.

Carson is neurosurgeon from Maryland. Although he is a remarkable physician, he has no previous experience in public office. His Christian faith is a cornerstone of his campaign, which is also mentioned in a long-form New Yorker article on Carson's rise to prominence. Much like Rubio, Carson's foreign policy plan focuses on American strength and America's relationship to other nations who have been foes of the US in the past. Domestically, he wants to dramatically reform the government bureaucracy. Naturally, health care plays a large part in Carson's campaign; the candidate wants to eliminate the Affordable Care Act and replace it with a system that allows private insurance companies to compete. Energy is of lesser importance for his campaign.

Chris Christie is the third candidate on the ballot in Oklahoma.

Christie is the governor of New Jersey. His conservative governance in a traditionally liberal state is touted by his campaign as proof of his ability to govern a diverse electorate. On the issue of criminal justice reform, he calls for reforms including "banning the box" and more re-reentry programs for criminal offenders. His foreign policy views focus less on viewing certain other countries as foes of the United States, although his energy policy is extremely similar to Carson's. Interestingly enough, his position on Medicaid and Medicare reform does not mention the Affordable Care Act.

He shares more of his foreign policy plan in this interview with The Atlantic.

Rick Santorum is after Christie on the ballot.

Santorum is a former US Representative and Senator from Pennsylvania. He won the Iowa caucuses in 2012, but he did not gain the Republican nomination that year. His energy policy falls into line with that of the two previous candidates - not extremely comprehensive. His plan to reform the tax system is fairly radical; it calls for the abolition of the current tax code in favor of a clean start. His foreign policy agenda is partly hidden within the tax plan on page 7; he favors abolishing non-humanitarian aid to countries that do not support American interests.  He does not have a dedicated foreign policy section on his campaign website; however, there is a page about America's fight with the so-called Islamic State (ISIS).

Here's a quick run-down of facts about Santorum from USA Today.

Arkansan Mike Huckabee is number five on the ballot.

Huckabee previously served as governor of the state of Arkansas. Although the issues portion of his website does not include a devoted foreign policy section, he does have a page on Israeli-US relations that is reinforced on the national security page. Huckabee's tax reform plan goes even further than Santorum's; it completely abolishes the income tax in favor of a national sales tax. His energy politics agenda does not mention any practical steps to be taken.

Carly Fiorina, the lone woman in the field, is right in the middle of the Oklahoma ballot.

Fiorina is a former CEO of Hewlett-Packard. Her website is set up differently than that of other candidates with the issues being presented as videoed answers to questions in addition to having the traditional written stances on issues. However, the written page gives little light on what her foreign policy goals would be beyond the Middle East. Additionally, her energy views are very similar to those of the other candidates.

Jeb Bush is the second Floridian in the race.

Bush, the brother and son of two previous presidents, served as governor of Florida. Energy seems to be a larger priority for him than for some other candidates; the page seems written to appeal to both moderate and conservative voters. Foreign policy, at least concerning ISIS, seems to be an area into which serious thought and planning has been put as well. Bush's campaign website stands out due to the large amount of content available, often with more substantive ideas than those from other candidates.

The Atlantic has an interesting take on Bush's candidacy.

John Kasich is next on our list.

Kasich is the current governor of Ohio and a former member of Congress. Like several other candidates, his take on foreign policy is presented as part of his national security plan.  His energy plan is similar to that stated by other candidates as well. In many issue areas, he cites his political record without offering his plan for the United States. A part of his plan is available here, but it does not encompass every area.

Here's a rundown of Kasich's views from PBS.

The campaign's most colorful candidate, Donald Trump, is next up.

Trump is a businessman from New York. His holdings, listed here, are numerous. Like Fiorina, Trump has been a supporter of conservative causes without having held political office before. His views are further to the right than those of other candidates; he advocates a wall at the southern border that will be paid for by Mexico. His positions seem largely motivated by his business background, including his plan for dealing with China economically. Unfortunately, he only has positions on 5 issues listed (China, the VA, tax code reform, gun rights, and immigration), which means that foreign policy and energy are both left uncovered.

The New Yorker wrote an article calling the election Trump's to lose.

Libertarian favorite Rand Paul is the penultimate candidate on the ballot.

Paul, a senator from Kentucky, is an ophthalmologist. Several of his issue areas are indicative of his libertarian beliefs, such as his pages on the NSA and government regulation. His tax plan is similar to Santorum's; he wishes to remove the current tax code in favor of a new system, although his plan to "audit the Fed" seems a bit behind the times. His foreign policy plan is simply national defense coupled with support for Israel, and his energy plan is nothing different than the ones that the other candidates offer. However, criminal justice reform seems to be an important issue for Paul which has several interesting proposals listed.

Here's a long form piece about Paul's life and politics from The New Yorker.

Last but not least is Ted Cruz.

Cruz, a lawyer, is a senator from Texas. Cruz does lay out an immigration reform plan, but does not have similarly detailed plans towards foreign policy beyond his support of Israel. He also supports a flat tax rate as part of radical reform of the US tax system. He would also eliminate the Department of Energy.

The New Yorker looked at Cruz's politics and the modern Republican Party in 2014.

__________
Final comments: Most of these candidates have similar views on the hot button GOP issues. Additionally, on their websites, they largely avoid written attacks on their fellow candidates, reserving their vitriol for President Obama and the Democratic candidates. (Exceptions to this include Kasich and Trump and to a certain extent, Paul and Cruz.)
