Reading this overview of a Reuters/Zogby poll, my advice to Dems is to solid and square: blame the Republicans. Clearly, the public elected a new congress in 2006 because they wanted a change from the failed, negligent status quo, but the GOP across the board has fought every substantive piece of legislation since the new congress got to work in January.
Blame Republicans. I think the voters will, but you guys need to be clear on your stands and the ways in which the filibuster and veto have been used to prevent the voters from getting what they elected: good government. Take 'em down, Dems.
