Hardly a rant Steve, more a simple case of human decency for being concerned about someone's health. Fetterman's performance during the debate (not just stumbling over words but only being able to understand what was being said after it had been transcribed for him) was enough to cause a legitimate concern for his health and his ability to recover while dealing with the stresses of being in office. Personally while I don't agree with a lot of his positions I think he seems to be a decent person but would have been better off keeping in the public eye and waiting till the next election to stand.
Mind you given that the Democrats managed to re-elect Anthony DeLuca to the House of Representatives with 85% of the vote despite the fact that he died on the 9th of October I'm not overly surprised.
