I consider the moderate wing those voters who are registered Democrats who are not swayed by the moonbats, always look at the candidates and issues, and weigh their options.
They then vote their conscious. Registered Republicans do the same, though they are more attuned to their conservative agenda.
The Real problem for Democrats is that the "Moderate Wing" has become REPUBLICAN over the last 20 years, as DEMS slide farther and farther to the left...
The 2004 DEM battles were not between the Center and the Left, they were between the EXTREME LEFT, and the SOMEWHERE OUT PAST PLUTO Left, with "Moderates" having no say whatsoever.....
