@Jeremiah,
Jeremiah, A good question, but to be realistic, it's only because of what Obama stands for and his character more than anything he promised during his campaigning. The facts are that no president will be able to do much with the current financial crisis and the two active wars in Iraq and Afghanistan.
McCain represents the old guard Bush ideas based on how McCain voted 4 out of 5 times with Bush. His rhetoric belies his actions; he voted 95% with Bush during the last congress. It doesn't matter how much McCain wants to separate himself from Bush, but only conservatives can't see the contradiction of his message against his past actions.
McCain's choice of Plain is very, very, poor judgment; especially since there are better conservative candidates for veep. Palin is all hat and no cattle. She even thinks the vice president has power over the Senate; which shows she has no knowledge of our form of government.
McCain has flip-flopped so often, I haven't heard any conservative outline for us what his position is on the major issues of our day. McCain talks about Obama as being a "socialist," but McCain also voted for the bailout/rescue plan that socializes our banks and finance companies. McCain goes further and says he will help people having problems with their mortgage buy it, and resell it to the buyer. Guess who buys their mortgage: the government. If that isn't socialism, I don't know the meaning of that word.
Also remember what McCain did when he said he was going to "stop his campaign" to go to Washington DC to help pass the bailout legislation. Even the republicans didn't follow his lead. That's leadership? He also lied, because he did not stop his campaign.
Palin is a rabble rouser that incites bigotry, hate, and violence. You want her as our leader?
Palin's foreign experience is, as she explained, that Russia and Canada are connected to "her" state of Alaska, and she can see them - and added to all that, her husband is a member to push for secession. Do you know how to spell "AMERICA FIRST?"
You do get the idea, don't you?
