A new PPP poll shows Graham Platner leading Susan Collins 49% to 45% in Maine’s U.S. Senate race. Matt questions the poll’s credibility, citing PPP’s partisan lean and past inaccuracies. He also notes recent polls have produced mixed results and warns that voter support can shift quickly if a candidate appears to be losing. While Platner is benefiting from being seen as a viable challenger, that support could fade if future polling trends turn negative.
