Outside groups aligned with Republicans have opened up a sizable ad-spending advantage in Maine, largely focused on defending Susan Collins. At the same time, recent polling shows Democrat Graham Platner ahead of Collins in a general-election test and far ahead in the Democratic primary. Platner is also drawing national attention with a planned rally alongside Elizabeth Warren. Heavy GOP-aligned spending to defend Collins could support her perceived strength, but polling showing a Democratic challenger ahead may add uncertainty. Overall, the news is mixed for Collins’ outlook.
