Are you able to call for hands outside your area? I’d be willing to travel and I’m sure there’s more than just me.
My suggestion to anyone who would like to volunteer to poll watch outside of their area is this: Pick a key area or key race that you want to support. Then contact the county level GOP for that location and ask how you can get involved. Here in Pennsylvania, you must have credentials to be at the polls, so it has to be done in advance. If you think of it at the last minute, there are surely still places to help with phone banking or driving people to polls, etc. Another avenue is to contact the campaign offices of key candidates and ask them for local guidance.
Anyone who would be willing to go poll watch in Philadelphia would be doing us a great service, but I wouldn't suggest any little ladies go it alone. (That's speaking as a woman of small stature.)
