Voter behavior and motivation (and knowledge of the issues, and of basic facts about their own government...) is well-studied and has been for decades. Political scientists studied it really heavily for quite a while because early results were fucking alarming (and proved to be accurate, and also not just a temporary aberration) if you're starting from a firm belief in liberal democracy and a broad franchise.
Voters, to a great extent, aren't motivated by what one might either expect or hope, nor 1/10th as well informed about the operation of their own government or the issues at stake as one might hope. It's a shit-show, so much so that it's practically miraculous that voting produces functioning governments ever, at all, and the whole thing's terribly fragile (after convincing themselves the data weren't wrong, the next step was a few decades of trying to figure out some mechanism by which this whole thing wasn't as worrisome as it seemed, which effort turned out to be based mostly on "copium", to use a modern term, and was eventually regarded as having more-or-less failed)
