Tonight, we’ll have another set of midterm debates. In Iowa, we’ll see the Republican nominee for US Senate, Ashley Hinson, face off against Democrat Josh Turek, a state representative and Paralympian at 8pm ET.

The race has become one of the most competitive of this cycle, despite the fact a Democrat hasn’t won a Senate election in the Hawkeye state since 2008. Turek, however, trails by just a point in a recent New York Times/Siena College poll. And Hinson, who currently serves as a congresswoman, has pushed back on Donald Trump’s agenda of late, as the president’s approval rating sinks to a new low. Hinson has called for an end on the war in Iran, despite consistently voting against House war powers resolutions that would curb military action, and criticizing the president’s recent pause on tariffs for foreign beef imports, which, Hinson argues, will affect the bottom line for the many cattle ranchers in Iowa.

At a rally in ruby red Nebraska on Monday night, Trump told supporters that he hoped to see a “tremendous victory” in the fast-approaching November midterm elections. He then suggested high prices due to the war with Iran were a “small price to pay for keeping the world safe – keeping our country safe”.
