Sen. John McCain was able to defend his chance for a sixth senate term by beating a Republican Tea Party activist in the Arizona primary. Sen. Marco Rubio of Florida also was victorious Tuesday night, after saying earlier in the year that he would not seek re-election. After stepping down as chairperson of the Democratic National Committee last month, Florida Rep. Debbie Wassermann Schultz was also able to win her primary.
