Even the New York Times acknowledges in a news article: "Across New York City, where Democrats outnumber Republicans seven to one, there are signs of Republicans making inroads. In the most recent midterm elections, every county in the city voted more Republican than it did in the 2020 presidential election, and three Democratic members of the State Assembly lost to Republicans in South Brooklyn."
The Times highlights Ari Kagan, a New York City Council member who, like Senator Sinema, is leaving the Democratic Party:
Mr. Kagan said that he believed that the Democratic Party, especially in New York, had drifted too far to the left.
"It's not me leaving the Democratic Party," Mr. Kagan said. "The Democratic Party started to leave me."
The Times doesn't mark the point, but this is a classic Reagan theme. Here is Reagan in a 1986 speech:
I know that it's kind of cliche to say, well, I didn't leave the party, the party left me. The funny thing is: It not only did that, but the party's changed. When I cast my first Democratic vote—21 years old—for Roosevelt, the Democratic Party platform called for a 25-percent reduction in the cost of government; the return of authority and autonomy to the States and local communities that had been unjustly seized by the Federal Government; and the elimination of useless agencies, bureaus, and commissions in the Federal Government. Which party today could run on that platform?
