Here is Tucson, we've got a Democrat Congresswoman in a Republican district. With McCain on the ticket, there is a good chance the Republican candidate for the seat will win (he is currently the State Senate President)
There will be a lot of one-hit wonders in 08.
Soros et.al. isn't going to run out of $ regardless of what is spent on the Presidential race. It's the GOP who is financially abandoning their candidates for Senate and the House to try to make McCain competitive against infinite amounts of $ from the billionaires on the left.
