Bollier seems alright. Have a feeling she'll be the nominee. She's already gotten one person to drop out. And I don't mind her. I'm personally to her left but, then again, I'm to the left of almost every politician in this state. I accept that as one the prices I pay for living in Kansas and not California. :)
She is courageous to a certain degree. But, her move might be accepted more here than in other red states. Kansas is one of the last red states where truly moderate Republicans can still be found in the wild. The moderates have been willing to endorse Democrats from time to time. Laura Kelly was the beneficiary of such in 2018. Many of them will probably endorse Bollier next year.
2020 should be an interesting election year. Kansas waffles between Trump being above or below water in approval. Kansas is also one of the leading states hit by farmer bankruptcies thanks to the tariffs. On top of that, Kelley has decent approval ratings and has been doing a good job. All this combined might make more people than usual willing to "hold their nose" and vote for a Democrat. Trump is almost certain to win, but the state races could be wild.
