The long US presidential campaign has made at least one young girl cry. In a video released Wednesday that has gone viral online, 4-year old girl Abby Evans is seen frowning, tears rolling down her cheeks. Her mother, Elizabeth Evans, asks why she is crying. Abby replies: "Because I'm tired of Bronco Obama and Mitt Romney."

Her mother then says the election will be over soon. "Yay," Abby says through her sobs.

Abby and her mother live in Colorado, a closely fought battleground state that has been pummeled with more than $83 million in campaign advertising.

Elizabeth Evans told KUSA-TV that her daughter started crying in the car while listening to an NPR report on the election.
