When someone tries to make you feel like you’re going insane, and that what you know is true is really just all in your head.
Whoa.
I like your description of gaslighting - essentially, convincing someone they are going insane when they are not.
But, the DNC isnt fooling of anyone - nobody is questioning their own sanity. The only thing the DNC is convincing anyone of is that they are liars and hypocrites.
So its not really gaslighting, per se - its just evil.
