Democrat, Republican..... all part of the establishment.
We need another course.
Two things:
1. How could a cartoon of unknown origin drive him out of the party?
2. What difference does it make anyway. I am sure there are thousands of so called, Republicans, who vote Dem every time. Many Pub Congressmen cannot be categorized any other way than to say they are openly Liberal Dems. They are all on the same side IMO. And that side is against the American people.
Per your tag line - be careful, liberals destroy everything they touch.
