AHC/WI: Fredrick Muhlenberg lives

The first and third Speaker of the House of Representatives was Fredrick Muhlenberg. He died at the age of 51 on June 4th, 1801. I've checked and haven't found why he died. Assuming he lives for another say 30 years, what would he do, which party would he involve himself in? He was Pro-Administration in his first Speakership, and anti in his second. Does he ever run for President? Pennsylvania Governor? Or does he not leave the House and builds a name there.
