Some of Sinclair's stations have a collective poll on their sites. The sites are all hosted on the same server, and share the same database of results, so voting at each of them may not have an effect.
I believe they will all report the results of the poll on their newscasts tonight or in the near future. Their most recent one was if you think there should be a draft (81% said no).
So I'm not sure voting at each of these will matter, but have fun, kids. Links after the jump.

And from the comments, the Star Tribune (Minneapolis, MN)'s poll.
