Dan Pfeiffer: “Maine is the most important Senate race in the country. Democrats have a narrow path to a majority, but they have no path if they cannot defeat Susan Collins in a state Kamala Harris won by seven points last year. Collins is the last Republican representing a truly blue state.”“Losing Maine wouldn’t just hurt Democrats in the near term; it would make it much less likely that a new Democratic president would have a Senate majority in 2029. The Senate map is so biased toward Republicans that we simply cannot afford to lose a single winnable seat.”“The high stakes really make me wonder what the hell Senate Democrats are doing in Maine.”
