in the hope that next time around enough (as in an electorally significant number of) people are angry enough that they actually push the Dems

You are demonstrating that you do not understand the most basic point of the analogy.

next time around enough (as in an electorally significant number of) people are angry enough that they actually push the Dems for what they want at the beginning of the term, not right at the end.

This is your thesis throughout this thread so please give examples of when the Democratic party have done inverted their position on a policy they didn't support at the election, on the basis that people lobbied for the change only immediately after the election.
