I've developed what I call "The Obama 2008 Vote Fraud Blood Spatter Light".
You take the 2008 presidential election by county, load it into a spreadsheet, then load the 2020 presidential "election" by county into the spreadsheet.
Compare the Obama number to the Biden number. If the Biden number is larger than the Obama 2008, compare the percentage that Biden beat Obama 2008 by.
If it's 108% or more, it's likely vote fraud.
I did Texas. The Demoscats targeted all the largest counties in Texas. The Obama Blood Spatter Light shows it like neon lights.
What they won't explain is why Trump actually gained voting share (not just sheer numbers) in the swing states of Ohio, Florida and Iowa under the same situation . . . plus a number of non-swing states ranging from Illinois to West Virginia.
