– Rob Portman –
Asked on NBC whom Trump should pick, former Republican vice president Dan Quayle immediately answered Portman, the 60-year-old senator from swing state Ohio.
Portman, whose calm temperament is the opposite of Trump’s, served as US Trade Representative and director of the Office of Management and Budget under George W. Bush.
– Newt Gingrich –
The speaker of the House of Representatives from 1995 to 1999 has broad name recognition – he ran for president in 2012 – and would provide vast knowledge about the workings of Congress.
Gingrich, 72, endorsed Trump and told Fox News he was in the “not no” column when it came to the veepstakes.
– Ben Carson –
Trump has said there is a 40 percent chance he will name a former nomination rival as his running mate.
Carson, a 64-year-old retired neurosurgeon, is now in Trump’s inner circle and was tasked with helping find potential VP picks. Having been the only African American in the race, he could help Trump with minority issues.
– John Kasich –
He only quit the race this month, and has said he is not interested in being vice president. But as the popular governor of Ohio and a former congressman, Kasich, 64, could bring Trump establishment experience and help win a crucial swing state.
– Female governor –
Trump is underwater when it comes to women voters, and a female running mate could help neutralize the gender debate.
He recently described 61-year-old Oklahoma Governor Mary Fallin, who has a good track record with conservatives, as “fabulous.”
South Carolina Governor Nikki Haley, 44, turned a toxic debate after a shooting tragedy into a political launchpad last year by ordering the Confederate flag removed from the state capitol.
Haley, the daughter of Indian immigrants, could also lend Trump credibility on the deeply divisive immigration issue.
