Seth Masket: “It’s always somewhat blurry just who is running for president, particularly at this early stage of the cycle. There are a few candidates who have explicitly announced they are running (Trump, Haley), a few whom are being treated as candidates even though they haven’t announced (DeSantis, Pence, Pompeo), and some who are clearly doing the things that presidential candidates do, but haven’t received much attention for it yet (Hutchinson, Scott).”
“I’ve put details of these in the spreadsheet. I’ve tried to keep these as simple as possible… By my count, we’ve had 15 candidates so far, and two of them (Ted Cruz last month and Larry Hogan today) have been winnowed out.”
