This statement is ludicrous. DeSantis was a nobody who only - barely - got elected because of Trump's endorsement. Without it he would have lost to a depraved crackhead. To claim he left the Congress with an "intent to run for president" is absurd.
Maybe. But his leadership lead to a 20 point win his second term.
I believe he already knew he was going to run for President when he ran for his second term as Governor. He just had to win to be able to use that position to throw his hat in the ring. Presidential races aren't created overnight. It takes some time to get all the ducks in a row to even make an announcement. He announced May 24, 2023. He'd only been 4 months into his second term at the time.
I believe he left Congress to be a Governor and then step up to the White House as soon as possible.
