One word, Obamacare.
The only thing is there were no political repercussions from passing that. To many bums, illegals, minorities, and freeloaders wanted it. There was tremendous political backlash from the passage of the 1994 ban. Tom Foley went from Speaker Of The House to citizen in one election night. The last time before that a SOTH did not get reelected was 1862. Even Clinton admitted it was all because of his support of the 1994 AWB. Don't think Harry Reid doesn't remember that.
