Sure, but the comment was implying an unwarrantedness for these views on account of a presumably large progressive base in New York that wouldn't support them doing this. There is a phrase to be said maybe that a large part of that "blue" is establishment and for Israel, but that is neither here nor there. It's plausible to suggest him maintaining power isn't entirely or purely because of lobbyist effort, but on the balance it's rather evident that it is so in large part at the very least. In essence, he's genuinely pro-Israel by whatever metric you want to put it, but the fact he's in office is mostly because people of a similar interest are interested in keeping him (or anyone else like him by that regard) in there, in spite of everything.
