Was easy in California, Washington, and Oregon. Republican is as rare as ivory billed woodpecker.

Wrong some state allows no observers

One System
 

IMHO, all elections should follow one specific set of rules. With PA allowing ballots to be counted three days after being received, as long as the postmark is dated the day of the election, makes it easier for the losing party to claim voter fraud. This is a federal election, and should folllow one format throughout the US. If PA allows three days after the election, then all states should allow it. We just can't go on with 52 states making up their own rules as to where, when, and how to cast ones vote.

I'll add Maryland to the list. Except for certain rare cases you aren't asked for any form of ID when you vote.

No both parties were NOT allowed to observe. At many of the vote counting facilities the other party was not allowed to come into the room to observe. At some they were not even allowed to come into the building! Some covered up the windows so others were not allowed to observe what was going on. To "observe" you need to be right there to actually see the votes counted and tabulated.
The decision to allow late mail-in votes as long as they were postmarked by Nov 3rd was another fraud. ANYONE with a postage machine can put any date they want on the mail. A party could have 100,000 fraud votes ready to go for any swing state and dump them late as needed and this happened.
Look on U-Tube and see the real time voting graph where one party was ahead in Wisconsin and then at 3 am a very unusual straight up line on the graph put the other party ahead.

California had 1/3 of the total vote Republicans this year.

I just spoke to my daughter on LI, NY. She was never asked for any ID when she voted. They asked her the first 3 letters of her last name and they said her first name and repeated her address. All she had to say is yes. The couple in front of her were told they had already voted, which was not true and were refused. They were told they had to go to the county voting office. Someone voted using their names. My granddaughter was still on the voter rolls in NY even though she is registered and voted in Florida. People still believe there was no fraud. HUMMM!

How did they determine which party counted the votes ?

Supression
 

So, what would you call it if not voter suppression and/or racism? The Post Master General is replaced by a billionaire that had no experience in postal operations, and the first thing he does is eliminate great number of sorting machines. Do you think that slows the process? How about a number of states limiting the number of drop off boxes? You think that might be akin to voter suppression? I know that I'd find it too inconvenient if I had to drive eight to gen miles in my county to drop off my vote at the only drop box in the county. This is especially problematic in the poorer sections of the community, where many people must rely on public transportation to get around.

"It's not the people who vote that count, it's the people who count the votes."

The Brennan Center’s seminal report on this issue.
The Truth About Voter Fraud, found that most reported incidents of voter fraud are actually traceable to other sources, such as clerical errors or bad data matching practices. The report reviewed elections that had been meticulously studied for voter fraud, and found incident rates between 0.0003 percent and 0.0025 percent. Given this tiny incident rate for voter impersonation fraud, it is more likely, the report noted, that an American “will be struck by lightning than that he/she will impersonate another voter at the polls.”

I was at the county offices getting a ballot as mine had been sent out of state to my mailing address. In the line with me was an elderly man that had to come in because his signatures didn’t match. His hand writing had become illegible. He was in a wheelchair and accompanied by his daughter. When I went to drop off my ballot, the woman taking it looked at my signature, scoffed and said in a nasty tone, “they probably aren’t going to accept this”. I didn’t know what to say. I mean, it’s my signature. So, here are two different examples of issues with mail-in ballots. How many elderly mail-in ballots were rejected and the member couldn’t get to a county office to verify, and how many last-minute ballots like mine might have been rejected?

Separate subject, but related, I just received a driver’s license renewal at my military home of record. I haven’t held a state driver’s license from them in years. FL was supposed to notify them when I was issued my driver’s license here. I’m still trying to correct this. Along with my license is voter registration, but I am registered here. So, I guess I have to ask, do the states ever talk to each other?

Mail-out ballots were an invitation for fraud and that system should not exist. Absentee ballots require that you, the voter, request the ballot. When a state mails out ballots for every registered voter, there are going to be problems because no state has up-to-date voter rolls. People move, people die. Someone is going to get those ballots and it's not the person intended.

When I moved from my northern state to Florida, it took me over two years to get my name off the rolls in my northern state and I was trying. Most people don't bother to try to clear their name off the voter rolls. It's a bad system.
