For better or worse this Pew study speaks volumes about the two parties and their ideological makeup:

Democrats
Conservative: 25
Liberal: 34
Moderate: 37

Republicans
Conservative: 68
Liberal: 4
Moderate: 25

Independents
Conservative: 30
Liberal: 20
Moderate: 45 

Republicans are completly relegated to the idoelogical extreme. Shouldn’t Mark Halpern or David Border write a column warning them of the danger they are in?
