99% of American voters have no problem with this whatsoever
If you've ever actually rolled up your sleeves and dealt with the American political system, what you'll quickly discover is that
Half your municipal candidates are just six real estate agents in a trench coat
Half your state candidates are the failsons and legal counsel of whichever rich assholes currently own the bulk of the real estate
Virtually all of your federal candidates are Ivy League schlubs who worked for someone in the party at the state or federal level in the last ten years
And these are the ones with the money, the time, and the social networks to productively run for office. Everyone else running is either a protest candidate with no name recognition or a delusional wacko with more money than sense.
These are the options on your ballot for the 99% of American voters who end up supporting on paper. The "true believers" tend to be the 20-30% of folks who try to research individual candidates and come back with heads full of hagiography. Whether they're people who got juiced up on Beto O'Rourke or Ted Cruz, they've got a mythological understanding of the candidate based on an endless deluge of propaganda produced by the party.
Then you've got the 1% of people who really truly do the ugly work of getting people elected. And they do get a look behind the curtain. But they either stomach the horror and truck on for ideological reasons or make a play for the cash option and just look for ways to monetize the rot.
In the case of Israel, there's enormous amounts of money to be had in the rot. Between weapons contractors, financial interests, real estate developers, and ideologically driven lobbyists, the Israel platform has oodles of cash to float itself. Nevermind the geopolitical interest of having a western allied power guarding the Mediterranean entrance to the Suez Canal.
This isn't a "voter" problem, because there's no real anti-Israeli option for voters available. 99% of American voters never get to choose another policy, because all the money is pointed in the direction of the Israelis.
