YouTube and PBS are partnering together on Video Your Vote, a project aimed at documenting and sharing the experience of voting with the world. On November 4th, you can submit your video to Video Your Vote's YouTube channel and watch all of the other videos being submitted from across the country. It's also a good way to hold polling places accountable for any kind of "procedural abnormalities."
On filming inside your designated polling place, Video Your Vote says:
Most states do allow you to film at your polling place. However, there are some states that expressly prohibit videotaping and others that have strict rules about how close you can tape near a polling place. For the most up-to-date information on your area, visit Documenting Your Vote.
They also mention that video doesn't have to just be of your experience while voting, it can be about your general thoughts on the election process. The most compelling videos will be shown on PBS's election coverage.
