2011–2012 election cycle

In 2012, 23 Democratic Senate seats were available, as opposed to 10 Republican seats. An increase of four seats would have given the GOP a Senate majority. In the election, three GOP seats were won and one Democratic seat was lost, increasing the Democratic majority by two. DSCC executive director said their strategy was to "localize" elections – make them "a choice between the two people on the ballot...and not simply allow it to be a nationalized election". Because this is not easy to do in a presidential election year, the DSCC had gone very much on the offensive, depicting Republican candidates and donors, and especially the

, as extreme. During the Florida and Indiana primaries, they pushed that the Tea Party was working to move the GOP "so far to the right that candidates will say anything to get their party's nomination". The GOP targeted four red states to pick up the seats they need for a Senate majority. They were looking at states that did not vote for President Obama in 2008: Missouri, Montana, Nebraska and North Dakota. They lost three of those four seats.


2013–2014 election cycle

In 2014, 21 Democrats were up for election. In order to have a majority, the Republicans were required to attain at least 51 seats in the Senate. The Democrats would have been able to retain a majority with 48 seats (assuming the two Independents continued to caucus with them) because, in event of a tie vote, Vice President Joe Biden becomes the tie-breaker. Many of the incumbents were elected in the Democratic wave year of 2008 along with President Obama's first election. Although Democrats saw some opportunities for pickups, the combination of Democratic retirements and numerous Democratic seats up for election in swing states and red states gave Republicans hopes of taking control of the Senate. 7 of the 21 states with Democratic seats up for election in 2014 had voted for Republican Mitt Romney in the 2012 presidential election. Democrats also faced the lower voter turnout that accompanies mid-term elections. By midnight ET, most major networks projected that the Republicans would take control of the Senate. The party held all three competitive Republican-held seats (

In 2016, 10 Democratic and 23 Republicans seats were up for reelection.
