It's mathematically possible for another candidate to enter the race as late as early February and still win enough delegates to take the nomination, though some deadlines for candidates to get on state ballots have already passed, including those in delegate-rich Virginia and Illinois. A late entry into the GOP race would come with potentially-overwhelming obstacles, including the need to instantly build a national campaign apparatus and do the hard work of getting on state ballots in an extremely compressed time period.

Who could pull this off?

Count me in that 58%. The only republican candidate whose domestic I can support is positively crackers on foreign policy, but, unless his domestic policies are implimented, and soon, we won’t be able to afford the robust foreign policy supported by the rest.
