IMHO, a Romney/Bush ticket makes sense...if they were running for the democratic nomination.
They felt each other about who might be VP in what case, but the overall goal of the meeting was to lay out the beginnings of a strategy to sabotage a Ted Cruz candidacy.
You can take that to the bank.
Given a choice of Hillary/Biden ticket or Bush/Romney ticket....man, I’d have to be mostly wasted on election day and just not remember who or what I voted for.
