Have you see their base lately? They have ginned that base up so rabidly for their constant marches, protest and riots that they can not govern for fear of having them turn on the leaders and get primaried.
What they have not figured out is the independents and conservative democrat are watching them in horror.
The left wing theory holds that if FTAA(South America) were added to CAFTA & NAFTA, and, 5 Federalists were on SCOTUS, then, the right case would come along and reach SCOTUS, in which, the five federalists would use the case to declare the New Deal to be unconstitutional.
The dems have been fighting the federalists since 2001, but they couldn't stop Alito and Roberts, giving 4 seats to the federalists.
This is why Trump got elected. He said he would change NAFTA so the left wingers abandoned Hillary and voted for Trump.
