The Republican National Committee is going on offense in the heat of campaign season, involving itself in election-related legal fights in several battleground states as ballots are finalized and early voting is around the corner.

The RNC filed an emergency application before the Supreme Court in Arizona this month over noncitizens voting and saw a partial victory. The committee just brought a lawsuit in Detroit because it wanted more Republicans watching over polling locations. And a lawsuit the RNC brought in North Carolina this week is one of many legal fights playing out over how states manage their voter rolls.
