If PA votes in a R governor, and the D wins the Senate, there is an even chance the governor will be selecting the Senate replacement in a few years.
The one problem with that scenario is that Oz probably has a better chance of winning than Mastriano does.
Hoping a Dem Senator is incapacitated so you can pick his replacement is a weird governing strategy. But nothing the Reps do these days surprises me. We continuously snatch defeat from the jaws of victory.
Doesn’t PA have special elections for Senate vacancies? Think Harris Wofford.
