If the election for the White House were based on the sale of campaign merchandise, Donald Trump would win by more than a hair — it’d be a huuuuge landslide.

“Trump is humongous,” said Times Square’s “Button Man,” Mort Berkowitz.

One of the biggest independent sellers of campaign merchandise in the country, Berkowitz said Trump has even surpassed the incredible selling power of President Obama.

“Obama was beyond belief,” Berkowitz said of America’s first black president, whose campaign buttons sold like hotcakes in 2008.

“Trump is beyond beyond belief,” the button-maker said.

That’s because people who both love and hate The Donald buy his pins.

Berkowitz has sold more than 18,000 Trump buttons, more than double all the other candidates combined.

“The Democratic clubs make money by reselling the Trump Hair button,” Berkowitz said. “There is nothing that competes with ‘The Hair’!”

If Clinton becomes the Democratic nominee, Berkowitz is ready to cash in on history in the making.

To commemorate the possibility, the “Bill Clinton for First Lady!” button shows someone handing the 42nd president a red dress.

“At least it’s not a blue dress,” quipped Berkowitz , referencing Clinton’s Monica Lewinsky intern scandal.
