This year there are some new weapons in their arsenals: cell phones apps. At least two conservative groups have already released applications intended for smartphones that allow anyone to get involved to report problems at the polls.
The group American Majority Action released an app this week BlackBerry, Android phones and iPhones. Users can take a picture of anything they're concerned about, and then, along with any additional details, submit their report, which is automatically stamped with the time and location.
Austin James, the group's media director, says that on Election Day American Majority Action staffers will be in a "war room," ready to pass on any allegations they believe are legitimate to state and local officials.
This election will be over control of the Senate and the House. Operatives in both parties are watching the same set of races, especially Senate elections in Nevada, Illinois, Washington and Pennsylvania that could determine control of the Senate.
With stakes that high, the legal battle could last well beyond any election day recount.
"If someone volunteers as a lawyer for a close election," former Republican National Committee General Counsel Jan Baran says, "they better be prepared to have a lousy Thanksgiving."
