You are playing stupid. Aside from Paul who is obviously not an enemy of Trump despite you including him in the list, neither Rubio nor Christie have any shot at ever being President. They're in the single digits support wise and Christie in particular is hated by a super majority of the Republican party. He is, to use your own language, a "ghost."
This is clearly what I meant, even though you are attempting to claim that a politically irrelevant person merely existing is proof that opposing Trump isn't deadly. If Trump's enemies aren't politically irrelevant, then they--like so many already--have retired or will soon retire. And
Either way, lumping in DeSantis with these irrelevant people makes DeSantis look even worse.
Chris Christie was a confidant of President Trump both before and after he was elected President. Christie was offered jobs in the first Trump administration, he was Trump's coach for the first debate against Joe Biden, and there is little doubt he would have been offered a job in the second Trump administration. The difference between Christie and Jeb Bush couldn't be greater...no comparison.
Beyond that...the notion that polls taken today offer meaningful insight on the 2024 race is just dumb. The electorate isn't focused on that and no one has even announced they're running.
