The divide is actually between "people who got an education that included critical thinking skills" and people who didn't.
Ideologically speaking, dozens of studies and surveys have shown that Americans are actually not very ideologically separate - it's just that the group that can't critically think is routinely and easily manipulated into voting AGAINST their own ideology through fear.
These posts are always a great illustration of why you simply cannot trust or pay any attention to polls.
#1 biggest issue here --> there are 0 Democrats who think Trump is a "Great" president. To believe something like this is an admission of stupidity and ignorance so profound as to be dangerous. There are people who TELL THE POLLSTERS THEY ARE DEMOCRATS but in actuality have likely never voted Democrat in their life. So when folks are going "Where are these Democrats that think he's doing great??" the answer is "they are nowhere because they aren't real."
This is easily verifiable by simply going online to Democratic spaces and looking with your own eyes. Go to Democratic rallies and look. Listen to Democratic influencers and find A SINGLE FUCKING ONE who has anything even REMOTELY POSITIVE to say.
You won't find one. Because there aren't any.
Now there may be some Democrats who, like another commenter mentioned, are so completely oblivious to the news that they may ACTUALLY think Trump has been "good", especially if they 1.) live in a white enclave, 2.) don't have any money tied up in stocks, and 3.) harbor anti-immigrant feelings (which is much more common than folks realizee). If you're living a life of total privilege AND are surrounded by the kind of "polite conservatives" most millionaires are, you'd think everything is great because EVERYONE AROUND YOU IS DOING FINE, IS HAPPY, AND IS THRIVING.
but GREAT? LOL you'd have to be pretty fucking stupid and live under a rock to think anyone who is a registered Democrat thinks Trump is "Great".
These polls - just like the ones people are pointing to as a way of dismissing the obvious election theft that just happened - are created by the Right-wing media apparatus as a way of pacifying people. My own father is a MAJOR, BIG DEAL elections guy and staunchly anti-Trump, but he waves away any and all conversation about 2024 being stolen because "the results were in the margin of the polls".
Polls are used as a means of pacification and must be ignored. If polls were accurate, they would have showed Trump losing across the board, since we know there were enough *purged Democratic ballots to give Kamala a 1.5% victory and flip at least 4 states to her. If polls were accurate, THOSE PEOPLE WOULD HAVE SHOWN UP IN THE POLLING THAT WAS BEING DONE BEFORE THEY GOT PURGED.
The fact NOBODY mentions that little fact is why we know that polls as they are used today are total bullshit, red-herrings meant to keep us from asking questions.
They aren't actually independents, they're just Republicans too embarrassed to admit it.
