No.
As I type I am watching DeSantis on a CNN Town Hall in New Hampshire. On Monday he said that he had a “ticket our of Iowa.” Maybe he meant a plane ticket back to Tallahassee, because there is no way forward for the Florida governor.
In New Hampshire (January 25), he is polling at under 10%.
In Nevada (February 8), he is polling at around 8%.
In South Carolina (February 24), he is polling around 7%.
In Michigan (March 3), he is polling at around 9%.
In Missouri (March 3), he is polling at around 14%.
If DeSantis drops out I imagine that much of his support will go to Trump.
Thomas Dewey minus the charm.
