Sen. John Fetterman (D-PA) was stumped cold when comedian Jon Stewart pressed him on where he draws the line for political support. "For you, you could agree with them 90 percent of the time, but Israel is the red line," Stewart said, seeking clarification from Fetterman on where he draws the line for his support. However, Stewart seemed baffled by why Fetterman draws that line. "But if they don't agree with you on Israel, you don't want them in your party." "It seems like a weird line to draw."
