I can't help viewing all of Bush's moves through the lens of national security. If this were just about buying votes, it really doesn't make sense if you go state-by-state: Texas is Bush Country and if California is in play, Bush has already won.
It does according to George will this afternoon on Sean Hanity's radio program
"Due to the tremendous changes in electoral demographics over just the past 4 years, if Bush maintains the same demographic percentages he did in the 2000 election he will loose by 2 million popular votes and will be wiped out in the electoral college"
Apparently Hispandering is a must for Bush.
