LOL. Instant fail.
Left-wing trolls are generally easy to spot. They're as subtle as a volcanic eruption. They'll open with something like, "I'm a Trump voter/ lifelong republican, but I'm concerned about [debunked story concerning Trump]." Or they'll follow with some nonsensical tirade that leaves them no reason to be republican. When asked a simple question, they'll start jumping from subject to subject.
They think it'll be easy, because they think we're all dumber than an empty beer can.
