This is a Very Smart Move

Donald Trump was on Jimmy Kimmel, and in response a question from the late night host, Trump said that he would be willing to debate Bernie Sanders, and Sanders promptly picked up the gauntlet:

On ABC's "Jimmy Kimmel Live!" Trump was asked if he would consider holding a debate with Sanders. Trump agreed to the idea.

"If he paid a sum toward charity I would love to do that," said the business mogul, noting that a Sanders vs. Trump debate "would have such high ratings."

In a campaign stop in North Dakota, Trump said Sanderrs would need to raise $10 million for charity in order for the debate to happen.

Sanders quickly responded with a tweet reading, "Game On. I look forward to debating Donald Trump in California before the June 7th primary."

I don't expect Trump to follow through, but there is no way that this is a losing proposition for Sanders.

If Trump backs out, he looks weak.

If Sanders does poorly in the debate, Clinton is not harmed, and her campaign gets a preview of Trump's debate performance.

Sanders gets another chance to sell his movement and his campaign.

If Bernie trounces Trump, he gives a big boost to his chances in California.

There are no downsides for Sanders, and only one downside for Clinton, here, and all likely outcomes are bad for the "Short Fingered Vulgarian."

Well played.
