WATCH: Booker Says the Person “Enjoying the Debate the Most Right Now is Donald Trump”

While Democrats took swipes at each other on the topic of healthcare during the CNN debate, Cory Booker made the wisecrack that “The person that’s enjoying this debate the most right now is Donald Trump.”

WATCH:

Before the debate began, President Trump tweeted:

Very low ratings for the Democratic Debate last night — they’re desperate for Trump!

Per Breitbart, the area outside the Fox Theatre was almost completely dead on Wednesday evening, ahead of the start of the second night of the second Democratic debate — a stark contrast to the boisterous crowds on the first night.

The debate, hosted by CNN, was to feature two of the frontrunners in the race for the nomination — former vice president Joe Biden and Sen. Kamala Harris (D-CA). The weather was fine; the setup was the same as on the first night.

About a dozen supporters of Rep. Tulsi Gabbard (D-HI) milled about, as well as a few supporters of businessman Andrew Yang and Biden.

But there was nothing like the dozens of supporters who came out on Tuesday evening to support spiritual guru Marianne Williamson. And the hundreds of left-wing demonstrators who marched in front of the venue — many of them supporters of Sen. Bernie Sanders (I-VT) — were nowhere to be seen.

It was, to borrow a phrase, “low-energy.”
