A Democratic veteran and iron worker announced Monday he will challenge Republican Paul Ryan for Wisconsin’s 1st Congressional District in 2018.

The long-shot bid will pit Randy Bryce against the most powerful member of the U.S. House. Ryan, former vice presidential candidate and current House speaker, has held the district in southeastern Wisconsin since 1999.

Bryce, a union leader who served in the U.S. Army, lost races for the Wisconsin’s Legislature in 2012 and 2014 and lost a 10-way primary for Racine County Board of Education in 2013. Bryce said he’s learned from the losses and is planning to raise at least $2 million for this run.

“I’ve learned a lot,” Bryce said. “The people of Wisconsin know who I am. I have community roots.”

A spokesman for Ryan had no immediate comment.
