Democrats are in step with modern times. Inclusion, equality, helping those who are sick, historically disadvantaged, the poor, the elderly. The ideology of the Dems as represented by their platform under the great President Obama needs no tweaking. It is infinitely superior to the stench represented by the regressive GOP.
The pressure is on Pubs to re-create themselves since their obsession with protecting the rich has never worked. This is difficult however because they flounder with their heads in the sand and a foot in their mouths.
Dems merely need to continue, presenting their superior solutions to the problems that plague this nation. We're still digging out of the Dubya Dark Ages with Republican obstructionism in Congress.
