He could of course, but I don't see Jeb as being particularly strong there (or anywhere, for that matter. Just wait until he gets skewered for Common Core and immigration reform).
According to polls, Jeb Bush seems extremely strong in every single Southern state except for the crucial ones like Florida*, Virginia and North Carolina. And outside of the South, he mostly does appallingly. Yet he has improved a million since only a few months ago, so obviously he's doing something right.
*Now, he seems to be the only GOPer to have any realistic chance to win Florida against Hillary whatsoever (Rubio for instance trails her by almost double digits there), but that doesn't say much, as Jeb, like everyone else, would be completely chanceless if he couldn't even win his own home state of Florida.
Yeah, but will Jeb keep his strength after going through the primary buzzsaw? His positions on Common Core and immigration are basically a giant "kick me" sign on his back, and the other dozen members of the clown car will be quite happy to do so.
