Arizona was home to several competitive statewide contests this year, many of which had national implications. It stood to reason that Sen. Kyrsten Sinema would be actively involved in the elections, hitting the campaign trail and rallying support for her allies.
But she didn’t. Sinema kept a noticeably low profile in her home state, expressing apparent indifference to the outcomes of the critically important races. Democratic Rep. Ruben Gallego appeared on MSNBC after the elections, explaining, “We fought as a team in Arizona and we won. Sen. Sinema was nowhere to be found. At all.”
A month later, the senator’s partisan passivity can be seen in a new light: Sinema didn’t seem to care about the Democratic Party, its candidates or its interests because she’s no longer an actual Democrat. The Arizona Republic reported this morning:
Sen. Kyrsten Sinema said Friday she is leaving the Democratic Party and will formally become an independent in a move that more fully places her at the center of a narrowly divided chamber. She announced her decision in an opinion piece published Friday in The Arizona Republic.
Sinema’s announcement makes her the first sitting senator to change party affiliations since Pennsylvania’s Arlen Specter switched from Republican to Democrat in 2009.
Today’s news, however, isn’t quite as dramatic.
Sinema has left the Democratic Party and changed her affiliation to independent, but she’ll continue to caucus with Senate Democrats. She won’t be alone on that front: Sens. Bernie Sanders of Vermont and Angus King of Maine are independents who’ve partnered with Democrats for many years.
The circumstances with Sinema will be a little different — she’s said she won’t attend caucus meetings, though of late, she’s generally skipped the gatherings anyway — but in her op-ed for the Republic, the senator suggested her policy positions and voting habits won’t change. She also expects to keep the same committee assignments — as chosen by Democratic leaders — that she currently enjoys.
Sinema added in an interview with Politico, “I don’t anticipate that anything will change about the Senate structure.”
In other words, as of 24 hours ago, Democrats looked forward to having what was effectively a 51-seat majority in the chamber. As of this morning, that remains largely unchanged.
So why bother? If Sinema is going to vote the same way as she’s always voted, and if she intends to remain effectively a part of the majority conference, why make a formal switch from Democrat to independent?
The answer is likely related to her 2024 prospects.
