So what, most of the 1% class support the Democrats. You have to go back a generation to find a period where the wealthy tended to vote Republican. The Republicans tend to be the party of the working class (a.k.a. the “deplorables” as the Democrats call them). Are you coming out in favor of a change in the law to ban rich people from donating to political parties, and to replace it with the government funding all campaigns, limited of course to those with socially acceptable views (a change the WOKE Democrats favor).
The closest thing to “rigging” was that in the Republican primaries, the Democrats funded candidates supported by Donald Trump, knowing that those candidates were likely to lose in the general election.
