- There is someone better. There is no one else.
- He thinks his chances are worse than those of an utter unknown such as French, someone he appeared willing to support.
- He thinks it is logistically or financially impossible; he’s been telling other potential candidates the opposite.
- He is unprepared to serve or lacks ideas for turning the country around.
- He fears an independent run would simply hand the election to Trump; he was willing to support such a run.
- He thinks Trump has improved or shown promise; if anything, Trump has become more erratic, spiteful and incoherent since sewing up the nomination. Romney in early March already saw that, with “Trump as our nominee, the prospects for a safe and prosperous future are greatly diminished.”
- He fears for his future viability as a candidate (as fresher Republican faces might); this plainly would be his swan song.
- He thinks he might lose. Well, of course he might — but he was willing to ask others to undertake the same risk of disappointment.
