it could happen, but you'd think people would learn. Having said that, most people hide behind convenient half truths. The tories, Boris, Trump and his lot are perfect for that type of voter.
"It's not my fault, I voted for trump because he said he'd fix things" - all signs showed he had no intention of doing so
"It's not my fault brexit was a mess, boris said he would fix it" - he was a well know liar even before brexit.
"It's not my fault the uk is broken, the tories said they would fix it" - their record has been awful since they got in, but you kept voting for them.
"It's not our fault the energy prices/trains etc are so high, it's the war/markets etc" - they've been in charge for years and built, maintained and allowed this to play out as it did and still has no intention of changing it.
