8. GW Bush, surprisingly.
It all came down to a few senators. Despite his many failings, GWB seems to be personally loyal. I’d say his loyalty to Jeb! underlies his antipathy to Trump.
And, here, he had personal loyalty to Kavanaugh who worked for him. So, he called a few senators. I think, most notably, he leaned on Susan Collins.
“GW Bush”
That’s really a stretch.
