What about Obama? Is he a liberal? He is by his rhetoric but not by his performance.
But you just said that liberals were the ones who nominated Kerry. Which is it?
I'll give you a hint.
Liberals opposed the invasion of Iraq.
Kerry and Hillary Clinton voted for it. They are both slightly right of center. It's just that the Republicans have moved so far right the center looks like the left to many. Reasonableness looks like a radical position.
There are very few liberals in the Congress. A handful. If you want an example of a liberal you have to look at somebody like the late Paul Wellstone.
