It wasn't just the republicans that passed the bill... apparently it was a unanimous vote (55 rep, 45 dem) and under the Presidency of Bill Clinton... hmmm.... let's blame republicans shall we....
Both parties have been moving to the Right, since Reagan. The most you can say is that Democrats have a slightly lower tendency to be corporate pawns than Republicans, but that's an uncomfortable argument to make. And in fact, it goes a lot more by industry. Since California and New York are such fundraising powerhouses for Democrats, they tend to support the technology, entertainment, and financial industries. Republicans support fossil fuels. Everyone supports defense, because defense contractors try to employ people in the maximum number of congressional districts.
Bernie represents the first real shift Leftward, in mainstream politics, in most of that time. Even though he lost, he made an impact on Hillary's platform.
But the problem isn't so much the Presidency as Congress. And I don't see any real change in that dynamic.
