Three candidates are making the case that he is the man to beat U.S. Rep. Steve Daines and keep Montana's U.S. Senate seat in Democratic hands.

Topics at the only scheduled Democratic debate between Sen. John Walsh, former Lt. Gov. John Bohlinger and Dirk Adams Saturday included big money in politics, the environment and civil liberties.

Bohlinger says the question that should unite them all is how to defeat Daines. The candidates invoked his name at least 16 times in the 1 ½-hour debate at Benefis Health Systems in Great Falls.

Adams attacked Walsh as a willing recipient of some of the same big donors who give to Daines.

Walsh responded Adams and Daines both agreed with the Supreme Court's Citizens United decision, which Adams denied.
