Both Alabama and North Carolina will have primary runoff elections for those races in which no candidate received more than 50% of the vote.  Runoffs tend to have lower voter participation than primaries and I urge you not to follow that trend.  If live in an area with a runoff please be sure to get out and vote.  You can find useful links for these primary runoffs below.
