I know a highly educated EDUCATOR that actually thought it was Sarah Palin that said “I can see Russia from my house”!! I told her to GOOGLE it since she wouldn’t believe ME.....she was flabberghasted! It didn’t change her Liberalness though!
Little things like that chip away at the walls of ignorance keeping people mired in liberalism. Do not argue or try to convince. Just keep showing her the evidence of leftist lies and challenge her to justify her positions. For instance, ask her why, if socialist policies are so wonderful, there are such high numbers of homeless in DemocRAT cities. And so forth. Bombarding her with accurate information and reason won’t work; the chipping at the liberal belief system has to occur slowly and in such a way that she starts questioning it on her own. If a person is redeemable, it can take time for them to start thinking rationally.
