I think I’m beginning to understand your reference or frame of mind. Since we both know the economy is going to do whatever it wants to do. That presidents really have nothing to do with it, no control over the economy. Hence those who blame Biden are stupid. Those who gave Trump and Obama credit for a good economy are also stupid. Those who blamed G.W. Bush for the recession are stupid. Going back to those who blamed Carter for the misery index and those who credited Reagan for the recovery are also stupid. Even blaming old Herbert Hoover for the depression was stupid.
But who’s fault is that? Republicans crowed about Trump’s good economy as did democrats giving Obama a ton of credit of avoiding a depression and reviving the economy. It all boils down to presidents and political parties taking credit for a good economy which they had nothing to do with it, they’ll get the blame for a bad economy.
Quite a lot of people vote the condition of their wallet. Sometimes for Democrats, other times for Republicans. Historically, voters have listed the economy as their number one issue in every presidential election since 1992.
So if voters are stupid, why do we continue to try to get more and more of them to vote? Perhaps, we need to go back to election day, just one day when everyone votes. People had to care to go to the polls and vote. Maybe they were more informed, maybe not. But they certainly had to be more motivated.
Here's something interesting, percentage of the general public that pays attention to politics. 38% of all adults are following politics leading up to the midterms.
