I'll never forget something that I heard on the local news on the day the electors voted for George W. Bush.
They said that in Louisiana between election day and December 18 (The day the electors voted), that thousands of registered democrats had switched to republican and that hundreds of registered republicans had switched to democrat.
I believe that the democrats' stunts in the 2000 presidential election contributed to their loss in the 2002 elections, along with other factors of course.
