Certainly. He has a young family and a wife who recently had cancer. But if he ever wants to be president, playing the wait-and-see game is not a good bet. He's most likely old news by 2028 (just ask Presidents Christie and Huckabee!)
Yeah, it’s 2024 or never. Just look at Cruz. His one shot to win was 2016, and now he’s a National laughing stock if he ever ran again.
Well, I could see him get another try in 2028 if he either comes very close at the nomination (and Trump subsequently losing) or DeSantis narrowly losing to Biden and overperforming expectations. However, both would require him to at least run in 2024. If he sits the election out, there's a high probability you're correct.
