If the 2016 election comes down to Hillary Clinton and Donald Trump, columnist George Will believes there would be a movement to draft a "real conservative candidate" for a third party.

On the same day that Sarah Palin endorsed Trump for president at a rally in Iowa, Will told conservative radio host Hugh Hewitt that it is just the latest episode in what he called the "silly season."

"Well, I don't think it's the Republican party turning a fresh face to a promising future," Will said when asked what he thought of the endorsement by the 2008 Republican vice presidential nominee.

"We should all believe in recycling, but there are limits frankly," he added, getting a laugh from Hewitt.

At Tuesday's rally, Trump opened up a new chapter in his ongoing fued with Will, as he went on a tear against pundits who have underestimated him as a candidate.

"Take away the glasses and he looks like a dumb guy," Trump said about Will.

Later in the interview, Hewitt, who is also a columnist for the Washington Examiner, said Trump is a "learning machine" and is getting better as a candidate all the time.

Hewitt asked Will, if Trump is the nominee in a contest versus Clinton, how many Democrats would cross over to the Republican side and vice versa if the former secretary of state is not indicted over the email scandal casting a shadow over her campaign.

While he predicted that more Democrats would migrate to the other party, Will suggested that this would not guarantee a simple one-beats-the-other scenario.

"You'd have to also figure, that there would be a movement to have a third party candidate, because if the election is Hillary Clinton against Donald Trump, this will be the first election since God knows when there was no real conservative candidate," Will said.

Will, having cast his very first vote for Barry Goldwater in 1964, whom he credited with leading the Republican Party back on the conservative track despite his defeat, said conservatives like him would not "sit idly by" and see the Republican Party disappear in 2016.
