I won't say that it hasn't occurred to me...is there any sort of argument that the big turnout and early voting doesn't indicate a thumping for trump? The assumption is that its driven by people desperate to get rid of foul fuck - and spooked by his blatant attempts at voter suppression. Or has everyone got it wrong and its driven by pro-trump enthusiasm and/or fear of evil commie biden?
But IN GENERAL infrequent voters tend to break for Dems when they do show up. There's a reason the GOP throw a lot of resources at ensuring people can't vote! Take Latinos - they're polling around 60-30 for Biden (they're actually more Trumpish than last time, probably because last time he was running a lot of rhetoric around the border wall that isn't being heard this time). Latinos tend not to turn out that highly for various reasons but they're def a largely Democratic electorate. In a state like Texas (or Arizona for that matter), if they turn out at a higher than usual rate then it's almost certainly bad news for the GOP who want their Good Ole Boys to vote and nobody else
That's the theory anyway
