Trump picked Pence for VP. Here’s who he passed up.

Originally published June 8.

Shore up Republican establishment support? Appeal to independent voters? Reinforce a populist, outsider campaign narrative? These are the kind of questions presidential nominees weigh when choosing their vice presidential nominees.

Trump’s pick could ease the fears of establishment Republicans.

Trump emerged victorious from the primaries, but he needs to unite the party, including many Republicans who are wary of his brash style and inexperience.

In an interview with The Washington Post in April, Trump said he was looking for “somebody that can walk into the Senate and who’s been friendly with these guys for 25 years, and people for 25 years. And can get things done. So I would 95 percent see myself picking a political person as opposed to somebody from the outside.” Tennessee Sen. Bob Corker would have fit the Senate-insider bill, but he removed himself from consideration on July 6.

Of course, there is still a chance his thinking on this could change. For instance, Trump could decide to go with a military figure such as David Petraeus. In May, The Fix’s Philip Bump made a surprisingly persusaive case for Trump to choose his daughter Ivanka.

Trump’s pick could improve his appeal among certain demographics.

For Trump to have any chance at winning in November, he’ll need to do something to mitigate his high unfavorability among Hispanic voters and women. Picking a woman could also make Clinton’s pitch for putting the first woman in the White House less effective.

Some potential obstacles for Trump: Govs. Nikki Haley of South Carolina and Susana Martinez of New Mexico have been outspoken critics of his, and it’s unclear whether they would even be open to consideration.

With the Senate’s balance of power very much in play, plucking certain senators from their seats could mean putting seats in play and possibly handing over Senate control. Sen. Kelly Ayotte is locked in a contentious, must-win Senate battle for Republicans in New Hampshire. An effort is underway to coax Sen. Marco Rubio of Florida into running for reelection after polls showed chances of Republicans losing that seat, too.

Trump’s pick could also be influenced by geographic concerns.

Trump has said he plans to turn industrial, and typically blue, Midwestern states red with his anti-free-trade message. He will also need to consider how important it is to choose someone from a swing state, but the jury seems to be out on whether a VP pick from such a place helps deliver that state’s electoral votes or whether it matters at all.

By picking Giuliani as his VP, Trump could effectively forfeit the state of New York, where both reside. The Constitution says a presidential ticket can’t win the electoral votes of a state where both candidates reside (though one of them could change their residency, as then-Texas resident Dick Cheney did in 2000). This likely wouldn’t matter to Trump, though, as Republicans are unlikely to compete for New York. With two New Yorkers leading the major party tickets, a running mate from elsewhere is likely.

Popular Ohio Gov. John Kasich would seem an obvious choice, especially given that he leads perhaps the most important swing state for Republicans, but a spokesman told the New York Times, “No chance.” Other swing-state folks in the mix include Sen. Joni Ernst of Iowa and Florida Gov. Rick Scott.
