So you automatically discredit Jeb Bush because you didn't like his brother when he was President? Besides his last name, what don't you like about Jeb Bush?
If you ask me, all three are the same person in three different bodies. All three would have invaded Iraq and all three would have done the same stupid crap. I'm not fond of the idea of risking another pointless war just so some warmongerer can impress daddy. Even if he's somehow different from the other two (which I don't think he is), the Bush name is ruined and they should probably retire from politics. We have enough political dynasties anyway.
There is absolutely nothing wrong with a man sharing and living out his faith in God. I'm glad that he speaks freely about his faith. It's a heck of a lot better than what the majority of the mainstream media carries on about every single day.
Nothing wrong with being religious, and he's a nice guy. However, I'm not religious, thus not fond of a president making political decisions based on their religious views, which I think he likely would. There's a reason we have a separation of church and state.
Also, I'm just not very fond of neo-conservativism in general. Ron Paul was cool, but that's because he's a libertarian and realizes how ridiculous our foreign policy is.
