jeb will do a solid job. Won't change much, it'll be similiar to 2001-2008, but that's to be expected. If you want change, then he's not the guy for you. If you want 'more of what we know', and you like the bush years, then he's a safe choice.
honestly, I'd rather have a RINO like Jeb in the race, than a mess like Hermann Cain, Palin, or Trump... Jeb knows the issues, they simply did not. When Cain said his solution to Libya was "9 9 9", it was terrifying. When trump started threatening China worse than any pres has in 30 years, in a flippant interview... terrifying. When palin spoke on any issue, completely confident while completely clueless... terrifying.
Jeb is more of the "not crazy about him, but safer than half the clown car options we saw".
