I picked Obama because I dislike his overall policies the most, and he has the momentum.
You can expect the same level of interventionism as the original Clinton era with all three, but Obama somehow has half of these people fooled into thinking he'll change the country into a Socialist Utopia that never goes to war. Unless it's Darfur, where alot of Liberals seem to want to go.
However, I would rather see Obama than Hillary, Obama can't manipulate Congress the same way that Hillary can. He's sure good at manipulating the people, though. Change Change Change!!!
Sure, he want's to change my 2nd Amendment
Civil Liberties.
He wants to Expand Fed. Spending
He wants to Increase Taxes
He IS an interventionist, as most Democrats are, even though people seem to have forgotten over the past 8 years. Have you forgotten that in the 20th Century 5 Dems havegotten America involved in foreign Wars, compared to only 2 Republicans? (T. Roosevelt, & Bush Sr.)
He IS in favor of more Foreign Aid spending
His Policies set the stage for continued Deflation, and continued Economic downfall.
McCain, on the other hand has I think 1 or 2 policies I semi-like.

I can't vote for any of the three, though.
