Biden: Clinton 'wins in a walk' if Trump nominated

Add Vice President Biden to the growing list of political leaders who have expressed alarm at the recent rhetoric from Republican presidential hopeful Donald Trump.

"I don’t know what his motive is, but I know what he’s preaching is a very, very dangerous brew for America," Biden said when asked by Bloomberg Politics about Trump's call to keep Muslims from entering the U.S.

The vice president was also skeptical of Trump's other immigration plans.

“I believe he’s smart enough to know half of what he’s saying makes no sense," Biden said. "Build a wall? He’s got to build a wall that’s the best wall and the highest wall?”

“A lot of this is showmanship," he added.

Biden sees a Trump presidency as extremely unlikely, however. He says that most of Trump's support is built on people "who are really frightened and scared" and therefore he won't be able to sustain his momentum.

If Trump were to obtain the GOP nomination, Hillary Clinton “wins in a walk” in the general election, Biden predicted.
