Senate Majority Leader Harry Reid (D-Nev.) said on Thursday that Mitt Romney gives “used car salesman a bad name.”

He made his remarks in Las Vegas, during his introduction of Vice President Biden, who was campaigning there.

“Now, Joe Biden stands for everything that’s fair and honest — he’s a man of integrity. The man that’s leading the Republican ticket for president of the United States is giving used car salesmen a bad name,” Reid said in his remarks introducing Biden. “Think about it for a minute: Have you ever seen anyone that would do anything, say anything like Mitt Romney?

“Remember on that last debate where he was whipped pretty good by Obama. He kept talking about the great things that he’d done in Massachusetts. Hey, folks, listen, he’s 20 points behind in Massachusetts. They don’t like him. He didn’t run for reelection because he couldn’t have been reelected. I repeat the people of Massachusetts don’t like him. He’s 20 points behind.”

Reid has been a vocal critic of the GOP nominee. Earlier in the campaign he claimed Romney didn’t pay taxes, a charge the Romney team refuted.
