Yes, definitely presidential caliber and he will run in 2024/28. Being a governor of Florida confers an immediate advantage in terms of name recognition/fundraising.
I think so as well. He's doing a great job down here. The people here on the forum complaining him aren't even in Florida. My life has barely changed at all since this started. I only wear a mask for five minutes a day. Only one person I vaguely know got sick (my youngest brother's teacher) but she recovered and school had already been canceled.
The lockdown's precedents are very alarming to me. DeSantis can lead the way by following Kemp's lead, but he is smart enough to know that it should be done in phases.
