How do Republicans explain losing 3 Congressional seats in 3 heavily Republican districts recently?

They failed to keep Bush in check and voted along party lines too much. Too many know Bush policies are stupid and just voted along to stay good with the party. Example, the Democrats wanted the Troops from Iraq to spend more time at home between missions, but they said no. The democrats want a better GI Bill, they said no. The Democrats want the Iraq government to start paying more for this war, the Republicans followed Bush. Actually,blame Bush and Cheny and Oh Rumpsfield!
