U.S. Rep. Dave Loebsack of Iowa’s second district, the lone Democrat in Iowa’s congressional delegation, announced Monday that he is endorsing Democratic presidential candidate Hillary Clinton in the 2016 Iowa Caucus.

“She has the ideas, the passion, the values that we need in our next president,” Loebsack said at the “Salute to Labor” picnic in the Quad Cities on Monday.

In 2008, Loebsack opted to endorse then-Illinois Sen. Barack Obama over Clinton.

“To put it simply, she knows how to work with others and get things done. That is why I’m proud to stand with her today and announce my support for Hillary Clinton for President,” he said.

The endorsement comes days after a new NBC News/Marist poll showed Vermont Sen. Bernie Sanders trimming Clinton’s lead in Iowa. Sanders has support from 37 percent of caucus goers compared to Clinton’s 48 percent, according to the poll.
