A video posted on Twitter appears to show a Pennsylvania voter attempting to change his ballot from Hillary Clinton and for Donald Trump, but being unable to do so.

The man repeatedly pushes the Trump/Pence portion of the ballot, but the red light does not switch from Clinton/Kaine.

He tweeted that the machine was “fixed,” but how many times did this happen without a voter noticing, or resigning to the fact that it wouldn’t change?
