I'm not disagreeing with you.  I'm just pointing out reality.  In your world with the lavender sky, every politician comes into office with the noble goal to only doing what's best for the nation.  In my world the sky is often dark, cloudy, raining - you know, the color of reality. 

Take a look at Murkowski's campaign press releases.  https://www.lisamurkowski.com/press-releases/
The vast majority of them tout her accomplishments at 'bringing home the pork'.  If they didn't help her get reelected, she wouldn't highlight them.  You can be sure every other candidate in every state is boasting about the same.  If our senators aren't scoring the pork, the other senators will.  Again, reality.
