As long as Republicans refuse to believe in mathematics, there will be no consequences, because they are telling their viewership exactly what they want to hear.
A perfect example of this was watching Kaylore, That One Guy, a few others, and most notably ColoradoDarin in the Election Day! thread. They kept saying things like, "why are we talking about polls when people are already voting?" and "I think we win Ohio because my sources tell me Democratic turnout is lower and Republican turnout is higher than in 2008."
That's what they wanted to hear, regardless of whether simple math (I'm talking 9th grade algebra and first year college statistics) shows them they are wrong.
It's a fundamental problem with the right these days, IMO. They're the ones who laugh about the lack of substance of "Hope and Change", yet when it comes to real, knowable things such as whether icebergs are melting, whether ocean levels are rising, whether voter fraud is an actual problem, whether the earth is older than 10,000 years, or whether an aggregate of polling methods provides a more accurate answer than one or two with flawed polling methods or "internal polling", they continually believe what they want to, regardless of facts and figures punching them right in the face.
This election, because of all those factors, should have proven once and for all the folly of favoring faith over fact.
Somehow I doubt anything changes for them.
