Susan Collins, one of the few remaining centrist Republicans in the U.S. Senate, has decided to stay in that polarized body rather than run for governor of Maine.
Collins told a crowd of roughly 100 business leaders and a throng of local and national media at the Samoset Resort in Rockport, Maine, on Friday that she will not seek the Republican nomination to run for governor next year. Instead, Collins said she will remain in the Senate at least until her current term ends in 2020.
