The article Keith talks about is over all very interesting and deserves a good reading over. A couple points in it really stuck out at me:
Mr. Rove has been responsible for the White House’s effort to ensure a GOP majority in Congress for the last two years of Bush's presidency. Internal party polls show the GOP could lose between 30 and 40 seats in the House as well as its majority in the Senate. A Democratic majority in the Senate would require the GOP to lose at least six seats.
This certainly goes against the talking points of the GOP, who tries to spin a more optimistic outlook. Even more interesting is the look into the overall plan for the GOP as seen by Karl Rove:
The source said that under Mr. Rove's plan, Mr. Lieberman would vote with the GOP on national security issues and help provide the party with a 50-50 split on major legislation. The deciding vote would then be cast by Vice President Dick Cheney.
