Deconstruct the argument that the Republicans have not caved to the Democrats when it mattered. Post facts as to where and when they stood up to the Democrats on issues and sent them running off with their tail between their legs. Cite chapter and verse. Name calling won' get you anywhere with me.
Just for your edification here is one example: Bill Clinton was President. Congress passed a bill forbidding partial birth abortion. Clinton vetoed it. The Senate overrode his veto and sent it to the House. It came down to one vote as to whether Clinton's veto would be sustained or overrode. A Republican cast the deciding vote to sustain it. That was one of many.
I don't hold the position that Republicans havn't caved. I've been all over spineless Boehner on that very point.
But I also don't hold following position...
Look, I think we all know that the odds are long. But there really is no choice but to try to change things. To see post after post that pretty much says that it will never happen to me is defeatist.
