Republican presidential candidate Mitt Romney greets supporters at a caucus in Portland, Maine, on Saturday.
Mitt Romney is three steps closer to the Republican presidential nomination, with victories last night in Maryland, Washington, D.C., and the key battleground state of Wisconsin. Romney showed strong gains among Tea Party voters and even evangelical Christians, according to exit polls.
Political insiders are starting to shift their attention from who the potential presidential candidate might be, to who might be his running mate. There will be no shortage of advice on that issue. Will the presumptive nominee look to fire up the conservative base or appeal to moderates? Are rivals Rick Santorum and Newt Gingrich on the short list? And in light of the last presidential election, how has the VP vetting process changed since the Sarah Palin days? Should Romney 'go rogue'?
