Blah, blah, blah! Woof, woof, woof!
The MSM pronounced the R Party's death in 1974-1976; Reagan got elected President in 1980, running against an incumbent President.
The MSM pronounced the R Party's death in 1996-2000; G. W. Bush got elected President in 2000, and reelected in 2004.
The MSM pronounced the R Party's death in 2008-2010; the Rs kicked D tail in the House and came close to capturing the Senate.
The MSM pronounced the R Party's death in 2012 and 2013; the Rs kicked D tail in the House, again, and captured the Senate.
The same sort of thing could be said of the Ds in the aftermath of the 2002 and 2004 elections, where they got hurt, yet recovered in 2006 and 2008.
The lesson is that predictions of the death of either the D or the R Party are fatuous at best. That said, let the DU-folk and self-deceived Ds expend their energy, lots of it, planning and rejoicing over the wake for the R Party they imagine can be held soon. Energy thus wasted won't be expended in winning elections.
