I will meet you half way. Yes, the GOP screwed up. SO WHAT?
They are now the minority party without even enough votes to stage a filibuster in the Senate. A more proper analogy for you might cutting off your nose to spite your face. The GOP wasn't perfect so you all fired them to elect the 0. And just what did that buy you? Every flaw in the GOP you stridently object multiplied 1000 times. Curious why you are so desperate to avoid ever holding the Democrat Party accountable?
Why avoid the 90% of the problem to fixate on the 10%? How about you actually try focusing at least some of your energy on the 90%?
Why spend all your time screaming about past mistakes rather then focusing on current ones? Seems to me all you are accomplishing here is deflecting legitimate criticism from the current regime onto the past one.
Which oddly is also the standard PR tactic of the 0 regime. Blame everything on the last regime rather then own up to it's current errors
We cannot ignore the fact that there is a third element at play here. It is the ever growing impact of lobbyists and the campaign funds they control. Both parties are controlled far too often and enjoy way to close of a relationship with the special interest groups.
Rather than start a third party or try to change the party from within, conservatives drive both parties to the right from outside the party. The Tea Party movement is the perfect vehicle for this. Fear of not getting reelected is a huge motivating factor.
Republican and even Democrats are not the real enemy - leftist special interest groups are the enemy.
