It's impossible to name the #1 Trump lie but...

[lame54]

If he convinces voters that coronavirus spread the last 6 months under the Biden administration

That would be a contender

1. I don't know what his number one lie is...

[Poiuyt]

3. And it includes someone calling him, "Sir."

2. Trump's #1 lie would start off with "I didn't do it ......... "

And then fill in the blank.

4. ...

6. To me the number one lie was about Obama's birth certificate. It helped give him

the oxygen of publicity to propel his campaign. It established him as the go-to racist/grievance candidate. It formed the core of his racist base, and it showed that the media could let him lie and not hold him to account, therefore opening the floodgates to more than ten thousand other lies.

7. #1 lie caused 200,000 deaths. So far.

It's a pretty easy question.

[lame54]

8. That's a series of lies...

Filled with contradictive lies

[lagomorph777]

9. Fair enough. #1 cloud of dishonesty.

10. I think his number 1 lie is his own self.

Trump, the person, is a lie.

All lies flow from that original lie.

Trump has to watch others to get a feel for an emotion that he then fakes as best he can. He fails miserably but he still has to take a cue from a person who can experience actual emotions.

He mimics facial expressions. He has his own - which are always those smarmy mouth contortions whether in anger or smirk-smiling. But when he tries to look like a human who experiences real emotions, he mimics other people. Like when he said he put on his Churchill look.

Trump is a damaged human. His true self is a snarling mess of fear and insecurity. A fear that lashes out in anger of being found out. Every attempt to appear normal, to appear not damaged, that he projects is a lie.
