I saw an article on the Torygraph titled something like "I voted for Israel in Eurovision to spite the woke", and there were people in the comments talking about how they'd sent in 20 votes for Israel. And others talking about how "the left" are relentless bullies for making the Israeli singer cry, etc.

I'm wouldn't be surprised if Israel did try to influence the votes, but I think there are plenty of right-wingers willing do do it for free, too.
