As great a president as he was, his biggest downfall was trying to compromise and work with Republicans. It didn't work, it didn't save his party from losing control of Congress, and it didn't cause the next Republican president to offer Democrats the same courtesy.
I hope the next time Democrats control both Congress and the presidency the Democrats learn from this and shun the Republicans from everything, and ram through everything they can without even the slightest bit of compromise. Because they know next time Republicans have control after that they're just going to do the same again.
Just like how you don't negotiate with terrorists, you also don't try to negotiate with right wing lunatics.
