You're over sinplyfing it. You don't need to be an "expert", but you do need to do more than read angry tweets to know and understand the depth of the issues.
Now now now let's not stoop to name calling. I don't think most people are "dumb", I think they are lazy and uneducated. Yes, absolutely they were fooled by misinformation. Below is just a SHORT list of outright lies and disinformation, but I'll make my point first and then you can read at your leisure. My point is this: these lies were either fully embraced leading to flately incorrect conclusions by voters, or if not wholly believed nonetheless created doubt leading to voters questioning and being less likely to accept the correct information being provided by the Democrats.
Trump falsely claimed that, “Over the past four years, Kamala and crooked Joe Biden have presided over an economic reign of terror, committing one financial atrocity after another. As Vice President, Kamala cast the deciding votes that caused the worst inflation in American history. You’re all victims of it. We all are.” In fact, the unemployment rate is low, inflation is way down, economic growth is solid, and job growth has been remarkably strong. Indeed, the country has added nearly 18m jobs, a record, under the Biden-Harris administration. Not only that, median household income has climbed to $80,610. The US has added more than 700,000 factory jobs. The Dow Jones Industrial Average is 36% higher than when Trump left office, and the S&P 500 is 53% higher. The US economy has grown twice as fast as Canada’s, three times as fast as France’s and Japan’s, and four times as fast as Britain’s.
Trump claimed in the June debate that “The country was growing like never before, and we were ready to start paying down debt.” However, on an equivalent basis, as debt accumulated per year in office, Trump saddled America with more debt than any president in U.S. history. Controlling for the effects from COVID-19, Biden-Harris still outperformed Trump.
Trump falsely claimed that immigrants take social security benefits and are decreasing the life of the program. In reality, immigrants cannot take social security benefits but pay taxes, thus increasing the life of the program
Trump falsely claimed that 107% of jobs are taken by illegal immigrants. In reality, native-born Americans have gained more jobs than illegal immigrants during Biden's administration.
In the lead up to the 2024 election, the Republican Party has made false claims of massive "noncitizen voting" by immigrants in an attempt to delegitimize the election if Trump loses.
Trump has falsely claimed that he was responsible for lowering insulin costs to $35 for those on Medicare, and has falsely claimed that Biden is taking credit for his accomplishment. Trump has falsely claimed that he was responsible for the VA Choice law passed by Obama.
During his campaign speeches, Trump erroneously asserted that the Biden administration was in the process of converting U.S. Army tanks into electrically powered vehicles.
Trump has falsely claimed that Democratic states are passing laws to allow executing babies after birth.
Trump has falsely claimed that schools are secretly sending children to have sex-change surgeries.
In the aftermath of the North Carolian hurricane, Trump engaged in several days of spreading lies, distortions, disinformation and conspiracy theories about the federal response, which public officials said created confusion and hindered recovery efforts. Among the false claims were that Biden wouldn't take calls from Georgia's governor; that Harris had stolen Federal Emergency Management Agency funds to house undocumented migrants; that the Biden administration was providing only $750 to people whose homes had been destroyed by the hurricane; and that no attempts had been made to rescue people.
Trump repeated a debunked hoax spread by neo-Nazi groups, right-wing politicians and media figures that immigrants were eating pets in Springfield, Ohio.
In the days leading up the election, Trump was falsely claiming all over social media that election cheating was actively happening. He was literally shouting it all over Twitter. Well, he won, so where did it go?
It actually wasn't completely clear and we've sorted it out.
Of course they want an effective president. My disappointment is two fold.
The first is that they didn't trade effectiveness for an "asshole", they traded effectiveness for a lying, grfiting, philandering, adultering, sexually abusive, mysogynistic, narcissist. Not everyone's perfect, but in the face of such moral depravity, you should be able to accept "less effective" (ie Harris).
Second, they didn't actually trade effectiveness for an asshole, because Trump won't actually be effective. He'll do things for sure, but they won't necessarily be good for the country, and they certainly won't be good for the vast majority of the lower and middle class people who voted for him.
