Mind you, Mayor 911 isn't actually endorsing Donald Trump, but he's doing the next best thing and voting for him.

“I support Trump. I’m gonna vote for Trump,” Giuliani said, according to the report.

Giuliani, who sought the Republican nomination in 2008, told the Post he has high expectations for Trump's performance in his home-state primary on April 19.

“It’s a question of how much he gets over 50 percent. If he wins 70 to 80 delegates, Donald has a good shot of securing the 1,237 delegates to secure the nomination before the convention,” he said, adding that he had met with Ted Cruz months ago before his comments about "New York values."

While acknowledging that Cruz was "attacking liberal Democratic values," Giuliani said "[t]here was a better way to say it.”

Perhaps he's hoping to be head of Trump's American Gestapo, should Trump win in November.
