Why do Trumpers hate the Lincoln Project?

Because the believed in great men like Ronald Regan not the immature con man like Lying Trump .

The Lincoln Project was run by old school Republicans who regularly ran attack ads against Trump in order to get him voted out of office.  It looks like their tactic worked.  😁

You realize that the whole thing fell apart, right? Go check your liberal sources as even they reported on the truth of the Lincoln Project and how they got exposed as a scam. 

"The Lincoln Project was plunged into even deeper turmoil Thursday, with the anti-Trump group tapping an outsider to investigate its handling of sexual misconduct allegations against a co-founder, and former employees demanding to be released from non-disclosure agreements."  LOL

To answer this, I would have to know what the Lincoln Project is. Does it involve time travel in an attempt to stop John Wilkes Booth?  Because that would create a paradox and destroy the universe. 

I don't hate them.  I actually kind of admire their hucksterism.    Lot of salivating lefties swooned over this group, lauding them with praise.  Cha-ching!

They speak the truth, especially about Trump.

They expose the truth about Trump!

Trumpers hate everyone, even other republicans, who tell the truth.
