I think the LibDems are the ones to watch. Being centrist has done them no harm. Something I suspect a lot of Tory MPs have noticed.
If all the MPs that don't support either candidate are more serious about their career than their rosette, they could do a lot worse than join the LibDems. Possibly making the Libdems (and themselves !!!) the official opposition.
The whole "you have to commit to leaving the ECHR" idea of Jenricks would be the clear blue water they needed. After all, no one signed up for that.
As for the JRM situation - he has repeatedly pulled his breeches down and invite Farage to have his way with his unworthy body. So Jenrick pinning him down as Tory chairman fits that particular metaphor. The fact it completely ignores Farages stated aim of destroying the Tory party forever will be a discussion note in the UK history taught in the 2200s ....
