Two good things, welfare reform and balanced budget, neither would have happened with the Democrats in control of the house. I doubt that the GOP would have taken the house if Bush Sr. had been reelected. In my own state of Washington the congressional district boundaries did not change between in 1992 and 1994, in those 2 elections the 1992 results were 8D/1R, 1994 results were 6R/3D.
So lets re-cap --- you're glad that Perot kept Bush from beating Clinton, because Bush's loss led to the House becoming Republican, which lead to welfare reform and a ( so-called) balanced budget for two years....
...which are basically the only things that Clinton can point to as part of his great legacy !
