If he were elected and unable to do the job, the governor of PA would appoint a replacement. So the word is, Democrats want people to vote for Fetterman, ignore all these health discussions, because a replacement Democrat would be appointed by the Democrat governor of PA, assuming that the Democrat wins the governor’s election.
The replacement could be his wife, or someone else.
Demo-rats don’t care if Fetterman is healthy or not - I suspect they think they have the fix in and just need to keep him in the race. ....Like they did Biden.
