“Most Democrats in Congress are united around the Democratic agenda, but a small number of senators and representatives have so far been able to hold up its passage. “I need 50 votes in the Senate. I have 48,” President Biden said last week, regarding his social spending bill. As for who is standing in the way, his blame was clear: “Two. Two people.”
Those two people are Sens. Joe Manchin and Kyrsten Sinema. The two moderates have forced Democrats to water down several priorities (such as election reform and the $3.5 trillion budget bill) and are blocking more ambitious reforms entirely (such as abolishing the filibuster). But while congressional observers — from the commander-in-chief on down — usually mention Manchin and Sinema in the same sentence, it’s a mistake to lump together their resistance to their party’s priorities. Manchin’s centrism is unsurprising: He has been a conservative Democrat his entire career, and his home state of West Virginia is so red that it might be politically impossible for him to move left, even if he wanted to.
But neither is true of Sinema. Once a staunch progressive, Arizona’s senior senator has taken a hard turn to the right. On the surface, that appears to have been an effort to make her more electable by courting moderate and conservative voters. If so, she may have overcompensated: Arizona is no West Virginia, and no other swing-state senator has vexed Democratic leadership so thoroughly. In fact, Sinema’s established such a firm anti-progressive reputation that she may have lost the support of enough Democrats to endanger her reelection just the same.”
…
“Democrats are lucky that Manchin is in the Senate at all. Because of how red West Virginia is, a typical senator from the state would almost certainly be a Republican.2 Indeed, based on Trump’s margin in West Virginia in 2016, we’d expect that a generic replacement for Manchin would have voted in line with Trump’s position 89.3 percent of the time during his presidency. Manchin, though, voted with Trump just 50.4 percent of the time — a lot for a Democrat, but not a lot considering the partisanship of his home state.
Using the same methodology, we’d have expected a generic replacement for Sinema to vote with Trump just 39.8 percent of the time — a reflection of the purpler partisanship of her state and her congressional district at the time. Yet Sinema voted with him 50.4 percent of the time too, as much as Manchin. That made her the only Democratic senator who voted with Trump significantly3 more often than expected based on the politics of senators’ states. Her voting record during the Trump years looked more like Manchin’s, Sen. Joe Donnelly’s, Sen. Heidi Heitkamp’s or Sen. Claire McCaskill’s — all Democrats from substantially redder states.”
…
“If Sinema is acting moderate for electoral reasons, she clearly disagrees with the conventional wisdom about how moderate a swing-state senator needs to be. On one hand, maybe she has a point: Donnelly, Heitkamp and McCaskill all lost reelection in 2018, as did Sen. Bill Nelson, whose home state of Florida is about as purple as Arizona but who voted with Trump less often than Sinema did. All four voted with Trump significantly less often than we’d have expected given the partisanship of their state, suggesting that Sinema’s strategy of hewing closer to expectations might have been smarter. (Although this doesn’t justify her approach of voting with Trump more often than expected.) On the other hand, political science research has found that candidates and congressional aides are really bad at assessing where voters stand on the issues. One 2013 study found that politicians overestimated by several percentage points how conservative their constituents were, in direct contradiction of Sinema’s entire theory of the case.”
…
“Sinema is presumably betting that Democrats who dislike her will vote for her regardless, and that at least some Republicans who like her will vote for her, too.”
…
“If Democratic opinion of Sinema sinks low enough, she could even be in danger of losing in a primary.”
…
“It may be her donors. In a September report, liberal group Accountable.US found that Sinema raised at least $923,065 from business interests that opposed Biden’s budget reconciliation plan, such as the U.S. Chamber of Commerce, a longtime Sinema ally. She’s also been the recipient of large donations from the pharmaceutical industry, which critics have blamed for her opposition to letting Medicare negotiate down drug costs. Of course, it’s possible that the causation is reversed — that such interest groups are donating to her because they like her positions on these issues.”
…
“Another explanation for Sinema’s centrism could be that she genuinely believes in it. In her 2009 book “Unite and Conquer,” Sinema described how she was initially frustrated at her inability to get things done in the state legislature — so she decided to stop being a “bomb-thrower” and start working with Republicans. Perhaps now, after so many years of embedding with the GOP to get things done (this is the first time she has ever served in a legislative chamber controlled by Democrats), she has internalized the conservatism of her peers — and even embraced bipartisanship as a policy goal unto itself. (That would explain her fierce opposition to ending the filibuster and her dogged negotiation of a bipartisan $1 trillion infrastructure bill earlier this year.)”
