Former Republican candidate Jeb Bush is meeting with all the remaining candidates other than Donald Trump, prompting speculation that he plans to endorse one of them as part of a party establishment strategy to prevent the nomination falling to the current frontrunner.

Privately, Bush has expressed regret that he exited the race when he did, back when the primary was still being decided based on policy and general bickering, but before it transitioned into a contest about who has the biggest hands. He says large hands run in the Bush family, which would have put him at a distinct advantage if he were still in.

Instead he now want to be sure he’s backing the man with the best chance of success going forward. Ted Cruz and Marco Rubio allowed a brief if awkward inspection of their wrists, palms, and digits, while John Kasich said he wasn’t the type of person to dance around an issue and promptly dropped trow.

Bush has yet to tip his hat about who he might endorse, though Kasich is hopeful. He has said nothing so far, though when Bush parted with Rubio he was overheard saying ‘Good luck with that’ as he gave his one-time protégé a knuckle cruncher of a handshake, and walked away smirking.
