MSNBC is reporting that Senate Majority Leader Harry Reid has held on to his Nevada Senate seat, defeating GOP challenger Sharron Angle by a margin of more than five percent. Fox and CNN have also called the race for Reid.

According to MSNBC, Reid won 90% of the Hispanic vote.

This is a convincing margin for Reid, who was expected to struggle to retain his job. Reid owes his political life to unions, youth voters and Latino/a voters.

With this strong win, especially in the face of the GOP wave, will anyone in the caucus dare challenge Reid for the leadership? (Update: MSNBC’s Howard Feinman says No.)
