((Carr resigned from the vice presidency and politics in general shortly before the primaries, so he wouldn't be an option.))
Hmm.
Well, let's see who we've got. Being Northern, Liberal, and Whig (not a Democrat voting for either of the Republican parties) would be beneficial to getting to such a role, and voting Cameron would put them in the party more likely to have taken a majority in the Senate and House.
-Brass, then? That would assume the Democratic-Republican party got a majority in the Senate, despite losing the Presidency.
-Vallejo, if no longer Sec. of Citizenship, could have gone back to either the House or Senate (now that he's old enough for that), and would be on the right party, although he's a Westerner.
-Hensdale, Khur, etc. are too non-Whig to stand much of a chance of getting that spot in the national and inter-party political landscape.
-We might still have
John Rus who voted for Cameron last election and is a Northern Whig.
-Cartright (or whoever he is now) and Walsh, perhaps, although they were Democrat before.
-
Senator Williams and
Senator Faust are Northern, Whig, and voted for Cameron.
