My friend Joe Chernov told me about his experience where a lawn sign advertising Massachusetts State Auditor candidate Mary Z. Connaughton dislodged from a truck delivering signs and crashed into his car as he was travelling on a highway. The sign impaled his bumper, causing damage that someone needs to pay for.
Chernov reached out to the candidate by email Twitter, and Facebook and included photos of his damaged car. But he got no response. And the Facebook message was deleted.
