You don't have to be a lawyer to be a poll watcher, observer, election judge or clerk. You just need to volunteer.
I volunteer every election to be an Alternate Election Judge (because I'm the blueberry in the tomato soup). I basically sit there for 12-14 hours, make sure the machines are set up properly, sealed, and that those voting are in the db. I also meet a lot of fascinating people. Including many that are voting for the first time.

You can talk to your the elections office in your county/district or talk to your local party.
This is true. I have volunteered in some capacity in every major election, and some minor ones, since the 2000 catastrophe, although my job currently precludes political activity. I was a poll watcher in the 2004 election, for the Dean campaign, although Dean had by that time effectively withdrawn. In the 2008 election, when I was a law student, I volunteered with my school's constitutional litigation clinic to do intake on the massive influx of first time voters who had made good faith efforts to register to vote in that election, but had been disenfranchised by an inefficient, unprepared process. Third years actually did the representation, and we won over 90 percent of those cases.
In the mid-terms in 2010, I got to argue a case (under a provision that allows third year law students to represent clients under supervision) and won that, so can therefore claim a 100% win rate. Interestingly, though, I had gone in with a losing argument, and only won because I had the sense to STFU when the Deputy Attorney General arguing the other side insisted on making an argument that was obviously infuriating the judge (for some reason the state attacked all these cases incredibly aggressively against the public policy of the state that election law is to be construed broadly in favor of enfranchisement). Even though it was an election day challenge, there were three political party lawyers there, from the two majors and the Libertarians, and then the head of my legal clinic. We got an order to vote to the voter, and got her to the poll, 10 minutes before the poll closed.
I love doing these election day things, and if I live to be in my 90s, plan to be one of those wonderful old people who are always at the polling places on election day. Whether they're Republicans or Democrats, and many of them are Republicans, they are all very eager to help everyone. I will gladly defend the franchise of anyone. Even a bagger.
