But he polls actually relatively well in South Carolina. So really this is even worse than doing nothing as he will reduce DeSantis' chances of winning South Carolina, an important early winner take all primary.
This is a consistent problem. For DeSantis to have a real shot at winning the primary he'll need to consolidate the field and keep pace with Trump on delegates. But if home state favorites like Scott and Sununu run, they'll reduce DeSantis' chances to pick up delegates in key early primaries.
Republicans are repeating all the missteps of 2016.
In fairness to Scott he's relatively lesser known among Republican voters. Those that know him like him more than most Republican candidates. So he's got upside potential. But I don't think he's got a realistic chance of winning the primary.
