Yeah, I get it. But we also use liberal and I think in this particular case its worth drawing the distinction between these two "camps" of the democratic party.
In every American community, you have varying shades of political opinion. One of the shadiest of these is the liberals. An outspoken group on many subjects. Ten degrees to the left of center in good times, ten degrees to the right of center if it affects them personally.
They haven't changed.
