Can someone explain to me how Obama is any different than Clinton or Bush?

The last 20 years we've had the same president, the only difference being one liked fat chicks, one liked Jesus, and one likes black people.

Can someone explain to me how;

Bush's medicare expansion is anydifferent than Obamas healthcare expansion?

Clinton's welfare reform is any different than Bush's compassionate consevativism?

How interveinig in the former Yougo, the ME, and ramping up troops in Afghan are any different?

We've been governed buy lame ducks since I've been born.

Since Obama has gotten into office he has been center left at best, while I don't agree with some of his ideas I believe he has a few good nuggets, however these want get any attention because he's a forigen born muslim communist who wants to eat beautifual blonde infants.
