Former New Mexico Gov. Bill Richardson told the ABC News/Yahoo News DNC Live Show today that he continues to feud with former President Bill Clinton after endorsing President Obama over Clinton's wife, Hillary Clinton, for president in 2008.

"The feud is ongoing and probably permanent," Richardson said. "I tried to reach out to him, but he doesn't care about guys like me. If he wants to continue isolating me, badmouthing me, that's fine. I'm fine."

Joining ABC News' Amy Walter and Rick Klein, Richardson also talked about how Clinton's appearance at the Democratic National Convention helps Obama.

"President Clinton is going to embrace president Obama, as he should," Richardson said. "They are working together. They're different kinds of people. Obama is cool, Clinton is a schmoozer. Both are great speakers. It's a great merging of the party."

He suggested Rep. Paul Ryan, R-Wis., was not necessarily the best running mate choice for the GOP.

"I just think the election will be settled by the Hispanic vote," Richardson said, "by Nevada, Colorado, Florida. I was personally afraid [Sen. Marco] Rubio [R-Fla.] would get on the ticket. I'm glad he didn't get on the ticket."
