A former adviser to President Bill Clinton argued Joe Biden has new competition for the Democratic presidential nomination.

“Biden thinks he has the nomination sewed up, but I’m not so sure,” Dick Morris told radio show host John Catsimatidis on Sunday.

Morris claimed New York Gov. Andrew Cuomo, who has been holding daily news briefings on the coronavirus pandemic, could be plotting to launch a last-minute bid to nab the nomination from Biden, who became the presumptive nominee last month.

“It is perfectly possible for Cuomo to replace Biden as the nominee. Biden has at the moment about 1,200 delegates, but you need 1,900 to win the nomination. And most of the states have postponed their primaries,” he said.

“New York, with over 200 delegates, has postponed its primary until June 23, the last in the country. I don’t think that’s a coincidence," he continued. "I think Cuomo may have postponed it so that he would increase his chances. You could have a write-in movement for Cuomo.”

Cuomo said last week he had no plans to run for president after President Trump said he would make a “stronger” general election opponent than Biden.

Morris has made bold predictions in the past that have failed to materialize. In February, he speculated that Hillary Clinton and Michael Bloomberg were plotting a way for her to become the nominee. He said Bloomberg, who dropped out of the race in early March, would continue his candidacy as a way to stop Vermont Sen. Bernie Sanders from running away with the nomination.

Instead, several centrist candidates ended their presidential bids before Super Tuesday, paving the way for Biden to surge past Sanders in the delegate count.
