This poll is meaningless.
Does anyone seriously believe for a nanosecond that IF Trump runs, he will not get the nomination? And does anyone believe for a nanosecond with his ego and his energy he will not run? His 78 is not a Biden 78. Trump is an anomaly. He will not be seen collapsing down steps like Hillary, and left to sit and mumble his way through things like senile ole Joe.
He will run, so this poll for now should focus on WHO he will select as his VP. That's the real question. Does he select someone that will be able to run in the next election, or does he pick someone to win a certain element of the electorate? Or to capture a coin toss state? DeSantis would be my #1 for VP to run for 2028. If he goes for attracting female voters, a stated weakness by the media with suburban women, then I would think Noem would be the choice.
Cruz will NEVER be the Republican candidate. He lacks integrity, I do not care how smart he is.
Or perhaps he picks another Pence type, someone of limited visibility that will support and help him. It will not be Pence again, his political career is over.
And this poll left out two perenials, the postman's son and Rick 'I came in second' Santorum. And then there will be a Ben Sasse, or someone that is a Never Trumper running like him. Count on it.
