Biden can get away with a ton of lying, to be sure. In all of his prior presidential campaigns, Biden's egregious lies cost him the primary. But following Trump, who lied like it was his job, the opposition was no longer able to call Biden on his lies without looking like obvious hypocrites.
Biden is still getting wrecked by fact-checks and community notes, it just usually doesn't matter since people tend to root for their political team no matter what. But lying about this isn't going to work.
He staked it all on Bidenomics (his administration embraced the term) starting in year one. He repeated the mantra that it is "working" over and over. He told people they were OK when they were not OK. Early into his presidency, over three-fourths of people said they had to make major life changes due to the economy.
Since then, it's gotten much worse.
Locally, my grocery stores are ending self-checkout due to theft. When there is a sale on something, even for just a dollar or two, people line up as though it is Black Friday. $10 products are getting locked up. The food drive near us now has a line that goes for blocks when it was previously almost never even used. The people in that line are some of my neighbours who live in million-dollar homes.
Politicians get away with lots of lying about the world because it's a big place, we have no way of seeing the evidence for ourselves, and, sadly, there is often a debate about if something was technically a lie or not.
But when basically 99% of people are hurting and he tells them that everything is actually better than before, sorry, that lie isn't going to work because we live the truth. We struggle with this reality every day.
Reports are showing that Biden is finally abandoning the strategy of touting the economy and going after Trump (a wise decision on his part) but the damage is done.
You don't get to pretend to love people while robbing them blind.
