DES MOINES, Iowa (AP) — The two Democrats vying to be Iowa's next U.S. senator each tried to explain in a debate Thursday why he's the one to flip the Republican-held seat, showcasing a struggle within the party over the best strategy to reclaim the U.S. Senate this fall.

State Rep. Josh Turek said he's the “battle-tested” candidate who has won in his red state House district by reaching independents and moderate Republicans who supported President Donald Trump. State Sen. Zach Wahls criticized national Democratic leaders, including Sen. Chuck Schumer, who he says have abandoned rural and working-class voters who are frustrated with both parties.
