This week, six polls showed Tommy Thompson losing support and falling behind in the U.S. Senate race.

Tommy Thompson’s response?

Thompson chose to stand with Mitt Romney and defend comments he made behind closed doors about “47%” of Americans.

Both Thompson and Romney have refused to release their own tax returns, yet both candidates have also put forth plans to raise taxes on the middle class and cut taxes for millionaires like themselves. As both Politifact and Huffington Post have reported, Thompson aide Brian Nemoir said Thompson’s tax plan ‘better balances’ the tax code by raising taxes on the middle class and cutting taxes for the top 1 percent of earners.

Now Thompson is blaming Romney for his own sagging support and fall in the polls and the Romney campaign is not happy.

As Roll Call reported, “It’s been a rough week for former Wisconsin Gov. and GOP Senate candidate Tommy Thompson, who learned tonight that GOP presidential nominee Mitt Romney has friends who are unafraid to lash out at other Republicans in his defense.”
