"As a presidential candidate and, more recently, as the chairman of the Senate Budget Committee, I've supported the struggles of working Americans in tough times and fought to give them a greater say in controlling their destiny. And frankly, I am frustrated by politicians who talk a good line about workers' rights on the campaign trail but then fail to deliver when they acquire power. That's bad policy, and bad politics. Democrats made an enormous and far-reaching mistake in the 1990s when President Bill Clinton aligned with Wall Street to approve so-called free-trade pacts, such as the North American Free Trade Agreement (NAFTA). Workers felt betrayed, and it cost the party dearly in the disastrous midterm elections of 1994, when control of the House and Senate shifted to right-wing Republicans who cynically exploited the opening Clinton had given them. Workers understood that you couldn't be both pro-Wall Street and pro-worker. For many working-class Americans, Clinton's choice to side with Wall Street was the end of their allegiance to the Democratic Party, a trend which has only grown over the years. Democrats should have learned their lesson. But there is very little evidence that this has happened. Too many of them still do not understand that the policies of a party that is supposed to stand for workers must actually do so when in power."
