Nathaniel, I think it's hard to undersell $17.7 million in outside spending in New York's 16th District race on behalf of Latimer or against Bowman. AdImpact says this was the most expensive primary ever, and about 4 in 5 dollars spent on ads in the race were from Latimer's side. Much of that was from the AIPAC-affiliated super PAC United Democracy Project, so the easy answer is to say Israel.

However, I don't want to overlook Bowman's various weaknesses and Latimer's strengths, which also were major contributors. Bowman wasn't strong to start with — he won only 54 percent of the primary vote in 2022 — and he'd suffered from more recent controversies such as pulling a fire alarm in a House office building and 9/11 conspiracy theory postings found on his old blog. Tellingly, groups like UDP mostly attacked Bowman for his past votes that didn't align with Biden rather than go after him on Israel. Latimer, meanwhile, has a long history in Westchester politics and may be about the strongest possible challenger Bowman could've gotten in this primary.

Nathaniel, I won't shy away from what I see as the big weaknesses for Bowman: Democratic progressives right now are upset at incumbents for the high cost of living and America's pro-Israel policies, so it's likely he lost some votes there — as evidenced by a projected decline in turnout from his constituency (from 90,000 votes in 2020 to around 70,000 today, if I reverse-engineer the AP's "expected vote" math).

But the bigger, um #ackshually answer I'll offer is that he was never that popular in the district. In 2020, when Bowman won his primary victory against unpopular incumbent moderate Democrat Eliot Engel, he won by only 14 points. And in 2022, he faced no real primary threat, inflating his appearance of a dominant incumbent.

The money spent for George Latimer by outside groups, of course, also likely has a lot to do with tonight's results. PACs don't spend over $20 million in U.S. House primary elections for nothing!

OK, guys, there are going to be a lot of hot takes out there tonight and tomorrow about why Bowman lost. But this is a smart, data-driven crew. What do you all think was the primary reason?

The AP projects that New York Rep. Claudia Tenney will win the Republican primary in New York's 24th District. We figured she was favored, but Tenney only defeated the same opponent, businessman Mario Fratto, by 14 points in the 2022 primary here, so we were keeping an eye on this one. However, with 36 percent of the expected vote reporting, Tenney leads 65 percent to 35 percent, per AP, so she looks set to survive and win reelection in this solidly red Upstate seat.

As Mary wrote earlier, only 3 percent of New Yorkers said that abortion was a key issue in advance of these primaries, down from 11 percent last year. Abortion access is protected in the state, but Democrats were hoping to nationalize it as an issue to win key races this fall. A vote for a Republican in the House or Senate, the thinking goes, is one step closer to a national abortion ban.

However, that strategy didn’t work for Klee Hood, who made access to abortion a centerpiece of her campaign. She lost to Mannion, who also supports abortion rights but also supports some restrictions after 24 weeks. If that issue isn’t as top of mind for New York voters, or other blue state voters, by the time November comes, that could make it harder for Democrats to gain an advantage in tighter general election races in close districts. That’s especially because voters do still care a lot about economic issues and rate Biden’s handling of the economy poorly. Whether abortion will be as much of a deciding factor this year as it was in the midterms, which proved to be good for Democrats, remains one of the biggest questions of this election cycle.
