The calls for the 81-year-old president to drop out have grown louder since his frail performance onstage at the first presidential debate last month, but the "Morning Joe" host said the dynamics had changed dramatically since his program signed off the day before.
"We've had so many momentous days over the last couple weeks," Scarborough said.
