Excerpt:
"Today I voted no on SB1485, the PEVL bill. I am supportive of the bill, but I informed leadership and the caucus that I was a no on election related bills because we are in the middle of an audit and there is talk of the Senate voting Sine Die in 2 weeks. Once we vote Sine Die and go home, we will not be able to fix any issues prior to the next primary election."
