But that was not the surprising part.

A note was left under the doormat of the couple’s home, reading ‘Hillary for Prison 2016,’ along with the couple’s SUV vandalized to the point where an auto shop called it unrepairable.

And if that was not enough, a few days later the Steadman’s 2-year-old Shepard mix named Abby got sick. The pup died Monday, as a result of ingesting a neurotoxin, according to the Steadman’s veterinarian.
