Past experience is no guarantee of future performance. The Dems enjoy once in a generation huge majorities in Congress and they occupy the WH. If they want to pass their socialist agenda--something they have been waiting for since LBJ--they must strike while the iron is hot. Whether electorally suicidal or not, this is their great opportunity to crash thru the barriers and put us on a path to socialism.
The Dems know that the midterms will put a major crimp in their ability to pass their agenda, so I believe they will push everything thru that they possibly can, including during the period after the midterms and January.
