Do you not recall the 2016 election? Clinton was ahead in the polls too. Yet we both know who's in the white house. A lot of folks don't openly admit they plan to vote for trump-hell a trump supporter was LITERALLY hunted down and killed. There is a pretty big silent group of folks who support trump, but just don't say so until voting time. Hell look at the support trump has-so many people coming out with signs- Biden had one guy with a sign when he went to I think Kenosha.
Also, why would you want a man who LITERALLY has dementia to be president? Even if trump is the biggest liar and PoS in the world, at least he's mentally sound. Also, Biden has lied throughout his career. Claiming he was top of his class, had multiple degrees, full scholarship, all lies he told in his first run for president. Then we have him spouting fake facts just to pander to folks. Claiming that Edison didn't invent the lightbulb and that a black guy did- didn't even mention the mans name. Who, did not invent it, but did improve it.
Even if you think trump is a liar, which he kinda is, Biden is just as big a liar if not bigger. Not to mention how Biden is having folks ask him scripted questions, and he's reading off a teleprompter. He's literally a bloody puppet at this point. And his VP is a very vile woman. A two faced snake that one. Who will ultimately take over once Biden finishes his job of being a Trojan Horse.
