President Barack Obama’s campaign has recruited a legion of lawyers to be on standby for this year’s election as legal disputes surrounding the voting process escalate.

Thousands of attorneys and support staffers have agreed to aid in the effort, providing a mass of legal support that appears to be unrivaled by Republicans or precedent. Obama’s campaign says it is particularly concerned about the implementation of new voter ID laws across the country, the possibility of anti-fraud activists challenging legitimate voters and the handling of voter registrations in the most competitive states.

Republicans are building their own legal teams for the election. They say they’re focused on preventing fraud — making sure people don’t vote unless they’re eligible — rather than turning away qualified voters.
