Who is to blame for the Republicans Defeat in 2006?

It is pretty clear that Republicans didn't fair well in the November elections here in Iowa. Republicans lost 2 seats in the United States House of Representives, lost the race for an open seat for Governor, lost 6 seats in the Iowa Senate where Democrats now hold a 31-19 advantage, lost control of the Iowa by losing 7 seats with Democrats now holding a 56-43 advantage. Democrats now have more Congressman, hold the Governorship, and hold both the State Senate and the Iowa House.

So who is to blame for the Republicans defeat in Iowa in 2006?

Christopher Rants, leader of the House Republicans? Nope, Rants was re-elected as Minority Leader in the House.

Mary Lundby, leader of the Senate Republicans? Nope, Lundby was re-elected as Minority Leader in the State Senate.

Ray Hoffman, chairman of the Republican Party of Iowa? Nope, Hoffman was just re-elected for the same position.

Maybe the Republicans want to blame the voters or do they blame the Democrats? They aren't blaming themselves.
