According to the nonpartisan organization GovTrack.us, Sinema is the most conservative Democrat in the Senate and has a voting record rated more conservative than Republican Senators Lisa Murkowski and Susan Collins. During Donald Trumps presidency she voted in agreement with him 50.4% of the time, the third-highest of any Democratic senator. (from wiki)
It could be said that the Senate has a Republican majority. Not sure thats what many Arizonans voted for, so I wonder if shes gone in 2024. OTOH, maybe a DINO is what most AZ independents really wanted.
