What bothers me about pretty much all the Republican candidates is that they're not "not Bush." It's like they made a lovely pie chart with all the factors of the Bush administration, broke it up, and gave each of the new candidates an individual chunk to supercharge and take to the next level. McCain is billing himself as the "national security" candidate, which basically means "Hey kids, do you like the current policy of invading Iraq and pissing off pretty much everyone else, but sometimes think it just isn't enough? Go World War III Xtreme with John McCain!!" Presumably, Romney appeals to people who want even more corporate tax cuts and such and Huckabee to those who think the main problem with Bush is that he just didn't hate the gays and non-Christians and scientists enough.
