This is unfortunately very likely.
Powerful pro Israeli groups hold the purse strings for vast amount of campaign funding.
AIPAC has formed a “Superpac” with a massive budget- it recently spent 4.6 million dollars on a single unsuccessful smear campaign against Californian candidate Dave Min. His criticisms of Israel were considered mild and did not even include calling for a ceasefire.
A PAC is a tax exempt political action committee that dispenses funds for its parent organisation. The New York Times claims that AIPAC plans to spend 100 million dollars via its super PAC fighting candidates who are critical of Israel’s role in the current conflict in Gaza. AIPAC’s own website claims that 98% of the 365 candidates they supported in the last election were successful
Another organisation, Democratic Majority for Israel, spent 1.4 million in 2020 on a successful smear campaign against Bernie Saunders that is believed have been critical in him falling from front place. This organisation claims a success rate of 85% with 28/29 wins. Funds are poring in for the next election.
So AIPAC will be pressuring politicians to withhold funding
