Political positions
Development initiatives

During the 2019 legislative session, Patterson refused to cast a vote on the End-of-Life Option Act, which would have provided palliative care to terminally ill adults, causing the bill to die in a tied 23–23 vote.[18][19] On his decision not to vote, Patterson said he had no regrets about decision, adding, "I did not cast a vote simply because I could not bring myself to move right or left on the bill and therefore I didn't vote on all. I don't know if it is [a violation of Senate rules] but I had to vote my conscience and that's what I did".[20] In 2020, when the bill was reintroduced, Patterson said that he would cast a vote if the bill came up for a vote again, but did not say how he planned to vote.[21][22]
