If Republican Congressman John Thune has decided his political future, he's not telling.
Many other Republicans are putting their plans on hold until Thune announces if he'll run for governor or the US Senate next year. Thune says there is a lot of curiosity, but he says it's too early for campaigns to begin.
Political scientist Bob Burns says a Senate race between Thune and Democratic Senator Tim Johnson could be an expensive one. He says they could probably raise more money than they could spend wisely.
