The dominoes have begun to fall. One of the seven Iowa Republicans seeking the GOP's U.S. Senate nomination has decided to run for the House instead.
David Young, former chief of staff to U.S. Sen. Chuck Grassley, R-Iowa, said Thursday he is switching races and will seek the party's nomination for the 3rd District House seat.
Young said that his goal was to work for Iowans in Congress.
"I can still do that in the House of Representatives," he said.
His announcement comes the same day Iowa Secretary of State Matt Schultz said on his Facebook page that he would have an "important and exciting" announcement concerning the 3rd District race next week. Schultz, who is up for re-election this year, also has expressed interest in the House seat.
The 3rd District seat is currently occupied by Rep. Tom Latham, but the Iowa Republican scrambled the state's political picture last month by announcing he wouldn't seek re-election.
That's led to a slew of politicians, Republican and Democrat, to assess their chances for the seat.
There had been speculation that the Senate field might thin, given the number of candidates and the fact that some are from within the 3rd District.
Young's exit from the Senate race, meanwhile, still leaves a crowded field of Republicans hoping to replace retiring Sen. Tom Harkin, D-Iowa.
Former U.S. attorney Matt Whitaker, state Sen. Joni Ernst, retired energy executive Mark Jacobs, radio talk show host Sam Clovis, auto salesman Scott Schaben and attorney Paul Lunde are all still in the hunt for the nomination.
It also could make it less likely that the nomination race could be thrown to a convention, which would happen if none of the candidates gets 35 percent of the vote.
Rep. Bruce Braley, D-Iowa, is the only Democrat seeking his part's nomination for the Senate seat.The filing deadline for the race is March 14.
