The democrats had a super majority under exPresident Obama and punted on immigration reform.
Wikipedia said:In the November 2008 elections, the Democratic Party increased its majorities in both chambers (including - when factoring in the two Democratic caucusing independents - a brief filibuster-proof 60-40 supermajority in the Senate), and with Barack Obama being sworn in as President on January 20, 2009, this gave a Democrats an overall federal government trifecta for the first time since the 103rd Congress in 1993.
However, the Senate supermajority only lasted for a period of 72 working days while the Senate was actually in session.
