The 2016 Senate elections occurred at the same time as the 2016 presidential election which saw Hillary Clinton elected president. Unlike previous years, it was now Republican senators who were under pressure having to defend 24 seats won in 2004 and 2010 in otherwise traditionally Democratic states compared to the Democrats' 10 seats with only two being competitive. Of the 6 seats that switched sides, 1 was won by the Republicans and 5 were won by the Democrats. Since this election happened to be a tie, the tie had to be broken by the Vice President. This means the Democrats had the majority until January 20th, 2017, under Joe Biden, and after that, the Republicans had the majority under Chris Christie. This is because the outgoing Senate had to pick the Vice President, and they picked Chris Christie.
