Gov. Chris Christie

Current job: Governor of New Jersey.

Reputation, in one sentence: An unapologetic Republican governor of a blue state who "tells it like it is"

Strengths: As Trump's first major endorser, Christie makes sense on several levels - he's combative and controversial (just like Trump is), he speaks his mind (ditto), and he's a two-term governor to boot. And Christie has already been named chairman of Trump's transition team.

Weaknesses: Christie probably doesn't help Trump in New Jersey, because the governor's approval rating in the state is in the 30s at best. And while it has disappeared from the headlines, that Bridgegate scandal hasn't 100% concluded — and that could be potentially problematic in the fall.

Sen. Bob Corker

Current job: United States Senator from Tennessee. Chairman of Foreign Relations committee.

Reputation, in one sentence: Pragmatist with a business background, focused on foreign policy vision and open to deal-making with Democrats.

Strengths: Trump picking Corker would definitely add foreign-policy chops to the GOP ticket, and would give Trump someone with legislative experience. Corker has become a validator for Trump by praising his recent foreign-policy speech.

Weaknesses: The Tennessee senator wouldn't expand the electoral map for Trump. Corker could also complicate Trump's narrative that he's the anti-establishment candidate, given that it doesn't get more establishment than being the chairman of the Senate Foreign Relations Committee. And Corker voted for the "Gang of Eight" comprehensive immigration-reform bill, and criticized Trump's Muslim ban.



Gov. Mary Fallin

Current job: Governor of Oklahoma. Reputation, in one sentence: First female governor of Oklahoma and a staunch conservative.

Strengths: If Trump is looking to add a woman to the ticket to counter Clinton's historical candidacy, Fallin could very well be the pick. She also served two terms in Congress before becoming Oklahoma governor. And she's more than open to being considered for the VP job. "My first and foremost goal right now is to finish our legislative session, but if I were to receive a call that said: 'I need you to help make America great again,' I'd be happy to take that call," she said.

Weaknesses: Hailing from red Oklahoma, Fallin doesn't help expand the battleground map. And she's never been considered one of the rising stars of her party - the same way that Gov. Nikki Haley and Sen. Marco Rubio were from that GOP Class of 2010.



Former House Speaker Newt Gingrich

Current job: Fox News contributor; advisor at Dentons law firm; author & public speaker. Reputation, in one sentence: Led the 1994 "Republican Revolution," passing sweeping legislation under the "Contract with America." Strengths: He'd certainly offer Trump legislative and congressional experience. And Gingrich has endured the scrutiny - and slings and arrows - of being a presidential candidate in 2012 and House speaker in the 1990s. Weaknesses: A Trump-Gingrich ticket would feature a combined six marriages between the two men. And if Trump wants to score points off of Monica Lewinsky and the Bill Clinton sex scandals, Gingrich could complicate that effort - givenGingrich's own extramarital affair during Clinton's impeachment.

Gov. Rick Scott

Current job: Governor of Florida. Reputation, in one sentence: A political survivor who's struggled with intra-party strife and low approval ratings.

Strengths: Before there was Donald Trump in 2016, there was Rick Scott in 2010 and 2014 - a man who used his wealth to win office in one of the most competitive states in the country. And if Trump wants help in all-important Florida, Scott could help, especially with the state's unemployment rate declining from above 10.0% when he took office to 4.9% now.

Weaknesses: But how much could he help? Both of Scott's wins came in midterm years when Democratic turnout was low. And despite his gubernatorial victories, Scott has never been a beloved political figure - see that video of him getting heckled at a Starbucks. Oh, and there's his work at Columbia/HCA hospitals, which was fined $1.7 billion by the U.S. government for health-care fraud committed while Scott was CEO there.



Sen. Jeff Sessions

Current job: United States Senator from Alabama. Serves on the Judiciary Committee and chairs its immigration subcommittee. Reputation, in one sentence: The Senate's most vehement opponent of comprehensive immigration reform. Strengths: If Trump wants to double down on the issue of immigration, Sessions makes sense - given that he's one of the most ardent opponents of both illegal and legal immigration in Congress. Sessions also would add legislative/congressional experience to the ticket. And Sessions was an earlier endorser of Trump. Weaknesses: Picking Sessions wouldn't add a lot of ideological diversity to the ticket, and it certainly wouldn't win over many Latino voters. In the 1980s, Sessions was blocked from becoming a federal judge after a former deputy accused him of making racially insensitive comments. "The former deputy, Thomas Figures, who was an assistant United States Attorney for seven years, said in a written statement that Mr. Sessions once admonished him to be careful about what he said 'to white folks.' Mr. Figures is black," the New York Times wrote back then. Sessions also was accused of mishandling a voter-fraud case against civil-rights activists.



Sen. John Thune

Current job: United States Senator from South Dakota. Currently serves as Senate Republican Conference chairman, the third-ranking lawmaker in GOP Senate leadership. Reputation, in one sentence: A telegenic party leader and strong fundraiser long considered a rising GOP star. Strengths: As the No. 3 Republican in Senate leadership, Thune as Trump's VP would further signal that the Republican establishment is coming around to Trump. He also would add congressional and legislative experience to the ticket. And Thune comes straight out of presidential central casting - tall, handsome, telegenic. Weaknesses: But selecting the establishment Thune would undercut one of Trump's selling points - that he's taking on Washington from the outside; Thune is about as inside as you can get. As the senator from red South Dakota, Thune also doesn't expand the map for Republicans.

Sen. Kelly Ayotte
