The current U.S. Senate has 54 Republicans and 45 Democrats (including one independent). The 2016 Senate election takes place on November 8, 2016. There are 34 seats up in 2016, of which 24 are held by Republicans. Democrats will need to gain 4 or 5 seats to take control.
Those numbers are as follows: Rehnquist 17; Bork 8; Thomas 13; Roberts 22; Alito 6; Sotomayor 9; and Kagan 6. So if history is any guide, Democrats need at least a 56-44 majority in the Senate to block a Republican-nominated justice. That means they must pick up 10 seats in 2016. The last such blowout for any Senate caucus was the 12-seat gain for Republicans in 1980.
