A spokesman for Daines, however, said the congressman has made no final decision on making a jump from the House to the Senate and is still considering his options.
When asked why Stapleton would indicate Daines is planning on running for Senate, Lockman said: “I can’t speak to what Mr. Stapleton’s thought process is.”
Daines has long said that he is seriously considering a run for the Senate.
The freshman member of the House briefly entered the Senate race in 2012 to unseat Sen. Jon Tester (D-Mont.). But he switched over to the House race after former Rep. Denny Rehberg (R-Mont.) announced his Senate campaign, attempting to avoid a “divisive” primary.
Daines’s campaign said he still has not set a timeline to make a final decision.
Republicans see Montana as a likely pickup in 2014, but the race remains largely unsettled. A number of high-profile Democrats in the state — including former Gov. Brian Schweitzer — have decided against a run.
