For Trump supporters to believe the election was stolen, means none of them paid any attention to what was happening in the general election campaign or to the polls. They must have gone into a cocoon and blocked the real world completely out. The writing was on the wall for everyone to see, if they could read that is.
Oh, they paid attention alright. And they refused to believe any of it.
We've discussed here before that the Republican voting base seems to operate in a different reality.
We were in the throes of the pandemic, there was no normal campaign, tension was running high, QAnon conspiracies flying, Donald Trump lying...it was an ugly time.
Then Biden won in a popular vote landslide. And they simply refused to believe it.
It had to be rigged...
Turns out it wasn't rigged.
