You don't think it makes sense? Hillary got more votes than Trump so why wouldn't Biden get more votes than Trump.For that matter we should expect Biden to get more votes than Obama because not only were there more eligible voters in 2020 compared to 2008 but more people voted so your argument is BS.
But let's look at some individual swing states and compare 2008 and 2020
WI, MI, IA - Obama got more votes in 2008 than Biden did in 2020.
AZ, GA, PA, NC - Biden got more votes in 2020 than Obama in 2008.
Trump got more votes than McCain in every state in the union comparing 2008 to 2012. Does that make sense to you?
Provide actual evidence for your claim or admit you have no evidence.
Down ticket elections can be gerrymandered. When it comes to Senate, more Democrats were on the ballot in Red states that Trump won. Then it leaves out the fact that many Republicans had stated openly that they couldn't support Trump.
Please provide your evidence of millions of unverified ballots. Then provide your evidence that millions of actual ballots only had Biden marked and no one else on the ballot. (Sidney Powell only claimed 450,000 ballots marked solely for Biden existed but provided no evidence is support of that claim.)
