My favorite was arguing with a much older (late 70s) friend of my dad's about how Obama ruined the economy and stock market, and when I told him that was objectively not true and the GFC was in full swing well before Obama was even elected, he was like "I know because I owned stocks and stuff, how would you even know?" Even when I pulled up a graph of the S&P 500 and showed the days he was elected and sworn in, he just said "Oh, that can't be right, the graph must be wrong". Showing the DOW and other composites from multiple sources did nothing to convince him. He was absolutely positive his retirement fund was doing great up until Obama was elected.

Yes Jerry, I'm sure that the entire stock market was just wrong, and it's not the fact you consume nothing but FOX News and will only refer to the 44th president as "The N*gger" potentially causing a bit of bias.
