It’s up to the states to administer elections. I don’t think the Feds can do much when it is at state level. However, it’s up the states to make sure that what happens in California doesn’t bleed into other states.
Lets see here; FLORIDA, GEORGIA, MARYLAND, NEW YORK, NEW JERSEY, PENNSYLVANIA, VIRGINIA, and probably a few more that I haven’t heard about (yet).
So don’t just blame California for this corrupt bullshit, the crooked democrats here in California were taught by EAST COASTERS.
(hell, most of the crooked dem pols here are from the east).
