Good. Then let Maine feel the Paine! They wanted her brilliance in the Senate and when they are on food stamps with fuel shortages they can thank her for her leadership.
If she's that new and bucked Senate leadership, she's in deep doo doo anyway.
Collins was REelected; she already held the Senate seat.
As for her bucking Senate leadership, you mean Republican Minority Senate leadership, which isn’t the same thing as if you were a Democrat and bucked Reid or Pelosi, for instance.
Nothing bad will happen to her unless it happens back in her home state, would be my guess.
She was reelected. This is her third term. IOW, she's already been there 12 years, and will be there another 6, AT LEAST ... in the normal course of affairs.
