Pennsylvania Lt. Gov. John Fetterman is running for US Senate. Still, his floundering performance on the campaign trail has left many questioning whether he is fit to run for office — or even serve in the upper chamber of the house.
After Fetterman had a stroke just days before his May primary, reporters were later informed he had a pacemaker and a defibrillator fitted to address atrial fibrillation. This serious heart condition was diagnosed years earlier but not revealed before he ran for public office.
He has relied mainly on his Twitter account of nearly 800k followers to charm voters in his absence.
