“Senator Susan Collins, Republican of Maine, is facing a moment like no other in her three decades in office, one that is testing whether her moderate brand of politics can survive perhaps the most polarizing presidency in modern history,” the New York Times reports.“Ms. Collins, a symbol of centrism and a paragon of decorum, has won five elections in a state that reliably votes for Democrats in presidential races by burnishing her reputation as an independent-minded Republican who delivers for Maine.””But this year, she is battling forces that are squeezing her from several directions: a working-class rage about rising prices, a call for generational change and, above all, a burning desire among many voters to make a statement against President Trump’s divisive second term.”
