I'm really unimpressed by Marco Rubio. Florida is only the 220th electoral vote or something, and I don't think he has as broad minority appeal in general. Best to nominate Bob McDonnell. Won't make a show of himself and lives in what may well be the 270th electoral vote.
From the way it is looking currently, Florida has a better chance of falling into the Republican column than Virginia.
Bob McDonnell is a walking embarrassment and no respectable Republican nominee can pick him now, seeing as he is essentially the poster boy for state governments restricting access to contraception and abortion and forcing women to undergo humiliation in the process.
McDonnell's already got his "VP" label, and it stands for 'Vaginal Prober'.
With that being said, I tend to agree with Rogue on this: Marco Rubio isn't nearly as good-looking in real life as he may be on demographic paper. I don't think there are any real solid choices for the Republican Party for VP in this election: there wasn't four years ago, and everybody on the stage at this point is brand new with virtually zero experience on the national level.
