Rep. Brendan Boyle, D-Pa., rejected the idea that Democrats should abandon attempts to pull in blue-collar voters.
"There is an element within the movement left that believes that we should just be the party of well-educated whites and racial minorities and leave blue-collar swaths behind," Boyle said Monday on MSNBC's "Morning Joe."
"I fully 100 percent reject that view," Boyle added.
Boyle noted some blue-collar areas that former President Barack Obama carried went to President Donald Trump in the 2016 election.
"They went for John Kerry, then went for Al Gore. So anyone who says we should, kind of, turn the page and reject those voters, first of all, I think it's wrong to begin with, and second, not in our political interests," Boyle said.
The congressman said that he felt confident about Democrats' chances in the midterm election. "We're always going to be the party, at our best, that stands for opportunity for all Americans, regardless of race, religion, or where you are on the socioeconomic ladder."
On Aug. 19, Boyle criticized President Trump, by apparently joking about a tweet from the president that praised those who speak out against bigotry.
