I disagree. There are plenty of moderate members of both parties, which is what I meant about forging coalitions. You don't have to start from a position of needing to "compromise" with the most extreme righties.
Honestly, it's about the only way any meaningful thing gets done. You want to go way left in the leadership & negotiations, you give power to the far right on the other side, and everyone digs their heels in depending on what letter comes after their name. That's how we get "moral" victories, but no practical change in our country.
Maybe the other school of thought will get lucky, and get an even bigger majority in Congress this fall with a Dem President, so they can just ram whatever they want through for 2 years. They'll only get 2 years that way, though. I'm interested in something more constructive, because fight club politics doesn't work, and never has.
