Keith Olbermann Calls Donald Trump "Most Dangerous Presidential Candidate" in Over a Century

"The hate that comes out between now and the election, if he's the nominee, does as much damage to the country as him being president," said the former MSNBC and ESPN host on Friday's 'The View,' where he talked about his op-ed announcing he was moving out of his Trump-owned building.

Keith Olbermann wasn't exaggerating about his negative views of Donald Trump's presidential campaign when he wrote his Washington Post op-ed announcing he was moving out of the Trump-owned New York City apartment building he lived in.

Appearing on ABC's The View on Friday, the former MSNBC and ESPN host lashed out at the GOP presidential frontrunner, calling him the "most dangerous presidential candidate" since a Civil War-era politician.

Summing up his argument, Olbermann recalled a recent conversation he had: "Someone said to me the other day, 'What would happen if ISIS got nukes?' … I said, 'What would happen if Donald Trump got nukes?' … Which is the most realistic concern for us at the moment? The second one is a distinct, visible possibility, and the first one is theoretical but unlikely because they're difficult to move. But he gets them the first day in office, so that's my problem."

And Olbermann said that even if Trump doesn't win the election, his ongoing campaign could be equally destructive.

"The hate that comes out between now and the election, if he's the nominee, does as much damage to the country as him being president," added Olbermann.

Still, Olbermann thinks the Republicans will ensure Trump is not nominated, explaining that if Trump continues on into the general election, "it could be the worst landslide ever."

"I don't think he has a reasonable chance of getting elected," said Olbermann. "And, at this point, from what I'm hearing, I don't think he's even going to get the nomination because I think the Republican party, everyone in the party who runs it, goes, 'If he wins, we all lose our jobs. If he loses, we all lose our jobs. Let's make sure he doesn't win.' "

He also called Trump's supporters "mostly people who can't really be trusted to find their own homes again once they leave them." And if Trump doesn't win, Olbermann thinks his business interests will suffer too.

"No one's going to do business with him," he added. "You couldn't bring this man into a business meeting."

As for Olbermann's own career: He left ESPN last year, and The View's Friday moderator, Joy Behar, said in closing that she hopes he gets "another show where you can spew your stuff," to which Olbermann said, "I'm coming out of retirement, so anybody who wants … "
