And most of them are controlled by matched partisan workers from the two parties from the precinct level on up.

At the state level the procedures and certification are handle by the secretary of state for that state.

The validity of each ballot is almost always decided by 1 Democrat and 1 Republican who know each other.

Even when there are problems the solution is arrived at by a consensus process.

In WA State a Governor's race was decided by a few dozen votes. After the polls were closed a few dozen ballots were found misplaced. If added they would reverse the Republican lead and give it to the Democrats.

Sec of State Sam Reed, a Republican, could have disallowed the ballots. He conducted a review and found that it was an accident and no malfeasance involved and gave the election to the Dems.

The greatest problem is Republicans putting in vote suppression actions (like picture ID) or fewer polls, shorter hours and fewer days. It is not uncommon for these policies to trigger higher turnout.

The federal government used to have civil actions and consent decrees yo control bad actions. Trump did away with all of that.

6 States shaved moved to all mail in ballots.

I used to work for SAFCOL Australia in Thailand and learned about A's mandatory system. My boss was a wild Aussie and he would write hilarious letters to the electoral Commission in crayon with misspellings and bad grammar to explain why he couldn't vote.

All subject to the normal(?) machiavellian processes that try to rob real people of their right to vote.

Not saying this is solely (r)epuglicon (witness Tamany Hall), but there seems to be a predominance of those activities.

It has almost no powers and is easily disabled by not keeping it sufficiently staffed - that's up to the excuse of a president we now have.

There are only three (out of six) active members - one Democrat and two Repuglicon. Two vacancies.

It's a token organization only.

Ellen Weintraub, the only Democrat is very vocal about the problems - see her on twitter.

Even the banana republic of Honduras has more strict voting system.
Largest democracy in world, India has issued 800 million voter ID cards with photo. No one can vote without them.
US elections are run by the several thousand counties individually.

One of the earliest actions of Trump was to neuter the Federal Elections Commission, with the blessings of (or instigation of) the GOP. We're in a slow-motion coup here, and the only reason that the Republicans didn't complete the coup was that they got cocky and assumed that they'd control the whole government for long enough to dismantle it, then 2018 hit and they lost the House.

I know a lot of people get frustrated that the House of Representatives has been "toothless" but the reality has always been that had we not taken back the House, we'd be a one-party state at this point.
