While in Iowa last week, former Vice President Joe Biden refused to explain in a video interview why Iowans should bother voting for him if they are experiencing a booming economy.

During an interview Friday with Denise Hnytka, a news anchor for local news station WQAD, Biden said “I’m not going to,” when asked to make his case on why Iowa voters should vote for him over President Donald Trump given the president’s record on the economy.

“In Iowa, the unemployment rate is 2.5% — people say they are employed in Iowa and their small businesses are growing,” a reporter said to Biden.

Biden interrupted the reporter and insisted that Iowans “were employed before [Trump] got elected,” and added, “I’m not saying he didn’t win by ten percentage points, I’m saying he’s not the reason the unemployment rate is down.”

The reporter still asked why people would “want to make a change” when they are experiencing such economic success.

“Well, that’s up to them to decide,” Biden replied.

“Why should they?” the reporter countered. “Make your case.”

“I’m not going to,” Biden said.

Biden is also currently dealing with a scandal over a January 2018 video clip that shows the former Vice President bragging about getting Ukraine to fire a top prosecutor who was looking into his son’s business dealings in exchange for a $1 billion guaranteed loan.
