Former HHS secretary to seek Senate seat
He has already been fending off attacks from both Democrats and more conservative Republicans over his position on President Barack Obama's healthcare reforms. Thompson spoke in support of reforms when the bill was working its way through Congress but now favors repeal.

Two other Republicans are also seeking the nomination: state Assembly Speaker Jeff Fitzgerald and former U.S. Rep. Mark Neumann.
