Hoping for a Democratic Party willing to get something other than impeachment done, former Sen. Joe Lieberman, I-Conn., called this the most partisan impeachment attempt in American history.

"Of the four impeachments we've had — Andrew Johnson 1868, President Nixon, President Clinton and now President Trump — this will probably the most partisan of all – although they all have been somewhat partisan, that's just the way it is," Lieberman told "The Cats Roundtable" on 970 AM-N.Y.

Lieberman longs for nonpartisan work in Congress and lauds former New York City Mayor Michael Bloomberg as a centrist hope for the Democratic primary.

"To me, as a centrist Democrat, he is more to my liking than some of the other candidates," Lieberman told host John Catsimatidis.

"He's going to be there to the end because he's not going to run out of money," Lieberman added. "I think the more people look at him, the more they are going to think about him."

The race to oppose President Donald Trump will be so close it might ultimately wind up undecided and render a "brokered" Democratic National Convention, Lieberman added.

"It's possible for the first time in a long time in American politics that one of the two major parties will get to their national convention without an obvious nominee," he said. "In other words, it will be undecided. We may go more than one ballot until we see who is going to be the Democratic nominee.

"And, I think, Mike Bloomberg entering this election increases that possibility."
