So, yes. Bellwether counties do not determine an election every time. The current bellwethers have only been in operation for forty years. They are almost always rural. In this election, most of the deciding counties were predominantly urban areas.
The logic you're using is that because Iowa, who has almost always determined the winning President every time chose Donald Trump, it is suspicious that Biden won the 2020 election. When, in fact, Iowa alone has only been right eight out of eleven times in forty years. Not to mention that the popular vote has accurately represented the Presidential win 54 out of the 59 votes. However, just as bellwethers do not determine the election results, neither does the popular vote.
As I've already indicated with my original statement that Reagan alone won more states than most Presidents have in the last forty years does not mean his election was any more suspicious than Biden's.
And suspicions of election fraud are not the same thing as evidence of mass election fraud. The only thing you've proven is that you're suspicious. Not evidence.
If there was evidence, Republicans would still be arguing about the 2020 election results. Pence would've not accepted the election results, or done so under great protest, and we would be in quite a political upheaval.
Instead, Republicans have changed tactics because this was never about election fraud but rather voter integrity. Which is the current issue at hand that any reasonable person would be arguing.
Not that the 2020 election was stolen.
