It was not the only Bush’s actions that lost congress. It was Congress’ lack of action. Bush and Cheney and about 3 others made the arguments for the Iraq war while the vast majority of GOPers cut and run from the argument. This left the dems and MSM 24/7 to get their anti-war voices placed each day on the front pages and airwaves. Then Abramhoff and Foley. Couple that with relative inaction on just about everything meaningful, they were toast. Do you even remember anything Frist or Hastert or John Boehner did or said during 2006, other than Denny complaining about the raid on William Jefferson’s house?
You are correct about the Repubs in Congress - especially the ones in the House of Lords.
They are as much to blame as the Administration.
Hastert was indeed the Tower of Jelly, and Snowe, Graham, Specter, etc, are no assets. They need to be purged.
