Every Iowa candidate seeking a statewide or federal office has agreed to at least one televised debate, with one exception: U.S. Representative Randy Feenstra. The Republican running for a second term in Iowa’s fourth Congressional district rejected an invitation from Iowa PBS without explanation. As a result, “Iowa Press” will interview Feenstra’s Democratic challenger Ryan Melton during the September 23 program, which had been set aside for the IA-04 debate.

Feenstra already backed out of a joint forum planned for the Clay County fair. According to Melton, the only joint appearance the incumbent agreed to was an event the Iowa Corn Growers Association hosted last week, which was not a debate and not open to the public.

In 2020, Feenstra debated his GOP primary opponents and Democrat J.D. Scholten during the general election campaign. What’s he worried about now?

To candidates who are behind, debates are “the thing with feathers.”

They offer one last chance to change the trajectory of a race. Historically they have mattered on occasion. In an unusual year, how they might matter is very, very, strange.

President Donald Trump’s unhinged and at times frightening behavior during his first televised debate “worried” and “alarmed” some of his most influential allies. The next day, U.S. Senate Majority Leader Mitch McConnell and other top Washington Republicans criticized the president’s failure to condemn white supremacists. Former Republican National Committee chair Marc Racicot even revealed that he had decided to vote for Democrat Joe Biden, after concluding Trump is “dangerous to the existence of the republic as we know it.”

True to form, Iowa Republicans offered no hint of dissent from the president this week. They either said nothing about Trump’s debate performance or put a positive spin on it.

The first clash between Donald Trump and Joe Biden was indisputably a low point in the history of presidential debates. There were plenty of discouraging moments, when Trump’s incessant bullying left moderator Chris Wallace pleading with the leader of the free world to stop interrupting. More frightening, a sitting president refused to condemn white supremacy and encouraged his far-right militant supporters to “stand back and stand by.”

But near the end, Biden delivered one of the best answers I’ve ever seen him give in a debate.

Since the advent of television, politics and indeed history have occasionally turned on a few moments. Seldom do they last longer than 60 seconds (like wit, television values brevity above all else).

Senator Joe McCarthy, and the moment he led, were stopped when he was asked, “Have you no decency, sir?” During the Watergate hearings, Howard Baker summed up the entire scandal when he asked, “What did the president know, and when did he know it?”

“You know, I haven’t heard Theresa Greenfield say one thing that Chuck Schumer hasn’t told her to say,” Senator Joni Ernst declared today on her Twitter feed. “And that’s not what Iowans expect in a leader.”

Several political reporters quickly noted the role reversal in Ernst’s call for six debates with her Democratic opponent. Usually challengers want more debates in order to raise their profiles before the general election. An incumbent making that demand is likely trailing, as the three most recent published polls on Iowa’s Senate race suggest.

Other endangered Republican senators have similarly called for frequent debates this fall, a sign of justified fear that President Donald Trump’s sinking approval will drag them down in November.

Another thing about Ernst’s taunt struck me as more strange, though. If she wants to make the election about who slavishly follows her party’s leader, Iowa’s junior senator is on exceptionally weak ground.
