Two things are required before you can change the rules of the game. You need to have a super majority and that super majority has to want to change the rules. AIPAC captured candidates are not likely to change the rules they rely on to stay funded and in power.

At this point Israel out spends the people on candidates, using US taxpayer money.

As far as the current administration and "fundraising" is concerned. They aren't fundraising, they are grifting.
