As a voter you are compelled to vote for the candidate with the largest campaign budget. Oh… wait, that isn’t true at all.
Money is important, but you still need to find voters that are interested in your message. If you have the money to activate them you can win, but they have to be there in the first place.
I agree, though I am super disdainful of any argument that is sort of reskinning “other people are really stupid”.
On the other hand, participation in a congressional primary is pretty low and should weed out the casuals. Nobody who is going to the polls without much info is probably going to show up for these right?
Further, when you have “safe” districts for your party, you sort of invite people from the entire political spectrum to participate in your primary. The parts of the American electorate that WANT muscular support for Israeli military operations are on the right. If those folks skip this primary, they have no influence over their representative at all. Activating conservative voters is probably easier than changing minds.
