2024 is not the same problem as 2016. The same tactics will not work.
2016 was a fractured field. There was no obvious consensus candidate. Trump could win the early primaries by pulling 20% of the vote. That will not be the case in 2016.
Even if there are six candidates on the stage, this thing is going to be DeSantis vs. Trump, with rough parity of support. If Trump pulls his usual scorched earth BS, he will pull 20% in the early primaries, and DeSantis will pull 40%.
On Trump’s best day, if he goes ugly, he will be lucky to get 50% support amongst Republicans. That will not be good enough.
2. What makes you think DeSantis is going to attract any more grassroots support than Jeb Bush did?
