Pew data is one example of data that shows this. Plus, in terms of Israel specifically, if you look at current support for the Iran war (which the Trump admin has repeatedly framed as important for Israels security) it's almost exclusively on the political right.
On the right, certainly the comments sections at least definitely feature some pretty alarming bigoted tropes--the comments explicitly make the jump from being about Israel to being about "the Jews".

One interesting comparison, the Twelve Day War against Iran in 2025 had Democrat support. Despite their rhetoric, they voted to give Israel huge emergency funding. But they're truly voting against the 2026 Iran War.
