Is Ron DeSantis running? From NBC: 

DeSantis recently launched a tax-exempt organization that sponsored his speaking engagements to police groups in New York and the Philadelphia and Chicago suburbs last week. He hosted a retreat for top donors from across the country at the Four Seasons in Palm Beach this weekend.

Sure, but he’s also a sitting governor, right? But what’s the No. 1 tell that someone is about to launch a presidential campaign? 

In 2014, Carly handed me the manuscript for her book Rising to the Challenge. It was her second book and opened with the police knocking on her door late one night. Her stepdaughter was dead from an overdose. It was a gut-wrenching story that hundreds of thousands of American families have experienced themselves. But it was also the surest sign that Carly was all in for a presidential run. Books are the new platform.
