I just assumed if Hatch succeeded the presidency, who would make the most sense for him to pick? It was between Marco Rubio and John Kasich. To be honest, Kasich might make more sense because he never endorsed Trump and has been publicly critical of him so it's possible that he could retain the public's trust sooner.Big Magilla wrote
In order for Rubio to leap over the current cabinet, he would have to become Vice President while Hatch is president. I thought of that scenario, but couldn't come up with a name. Rubio seems as likely as any.
That said, considering we don't really have the votes to impeach Trump anyway, I don't see us having either the votes or the constitution to oust Pence or Ryan.
