With regard to Decaturguy’s post, I think we should bear in mind a couple of points.
First, nationally the Democrat popular vote share was 51.1% — if George Bush’s 51.4% of the vote was no mandate for governance, surely this is not.
Second, while the Democrats consolidated their hold on New England, to get their majority they needed to pick off a number of swing districts that went for Bush in 2004 and tilt very slightly Republican. They took those districts with an average of 1.5% in excess of the GOP.
It’s a little early to be singing the destruction of the GOP — especially when they just made gains in Georgia.
