I'd say if the election were held today, DeSantis would lose, Rubio would win. But it's not, it's 13 months off and a lot can happen between now and then. I do agree with Republican don't legislate, the only legislation I remember during Trump was his tax cuts. I don't remember him proposing any other major legislation.
On governing by EO's, Obama did exactly that his last 6 years. Which worked when he was president, but when a new president enters office, the new president can repeal, revoke, change previous president's EO's which is what Trump did. Trump spend more time rescinding EO's than initiating them. At least that how it seemed to me. Trump was doing everything he could to eliminate anything Obama did to include any legacy.
I don't think Trump will run again in 2024. If he did, the only candidate I think he'd stand a chance of winning against would be Harris. Independents don't like either one, but dislike Harris more than Trump. A repeat of 2016 with Clinton and Trump.It also seems to me, a lot of independents have over the last month and a half to two months assigned Trump to the dust bin of ancient history. Another run for the presidency would bring out all the old reasons why they, independents disliked Trump and got rid of him.
But who knows? No one knows what will happen between now and Nov 2024, what unforeseen events or how the public as a whole will view or perceive Biden's and democratic rule.
