What's The Point of That Woman?

I understand why Tom Coburn wants to be in Congress.

Ditto Marsha Blackburn or Marco Rubio or Deb Fischer or even Steve King. These people have policy priorities and political changes they wish to accomplish -- ones I disagree with, to be sure, but they have them -- and being in Congress is a solid mechanism to turn their dreams (also known as my nightmares) into reality.

But I do not really understand why Susan Collins has any desire to be in the Senate. What motivates her? What causes her to get up in the morning? What exactly is she hoping to accomplish?

I don't think she really harbors any deep desire to put our tax code through a wood-chipper to benefit the ultra-wealthy while decimating students and the working-class. Were she running the show, there's no way she'd produce a tax plan even remotely similar to the one that she just voted for. At the same time, she obviously doesn't have any interest in actually voting against her Republican colleagues more than once in a blue moon, or putting up more than token resistance to policies she'd never draft were she the one in charge. She's the epitome of a moderate Republican: someone who talks about voting against Republican proposals before voting for Republican proposals.

So what's the point? Why does she bother?

I mean that honestly. I have no idea what motivates Susan Collins. I do not understand what drives her. She appears to exist in order to roll over.

Why would one want to live that life? It's baffling to me.
