Discussed here. Myth Number 3 deserves to be excerpted, since it will cause the netroots some serious heartburn:
3. Now that they control the White House and Congress, Democrats will usher in a new progressive era.
Not likely. At first glance, the numbers do look encouraging for proponents of a new New Deal era in government: Obama claimed at least 364 electoral votes and more than 52.5 percent of the overall popular vote, while Democrats now control at least 57 seats in the Senate and 255 in the House.
But look more closely, and you see a heavy influx of moderate to conservative members in the incoming freshman Democratic class, particularly in the House. Of the 24 Republican-held districts that Democrats won in 2008, Kerry carried just three in 2004. Democratic victories on Nov. 4 included Alabama’s 2nd district (where Kerry took 33 percent of the vote) and Idaho’s at-large seat (where Kerry won just 30 percent). In fact, according to tabulations by National Journal’s Richard E. Cohen, 81 House Democrats in the 111th Congress will represent districts that Bush carried in 2004.
The fact that roughly a third of the Democratic House majority sits in seats with Republican underpinnings (at least at the presidential level) is almost certain to keep a liberal dream agenda from moving through Congress. The first rule of politics is survival, and if these new arrivals to Washington want to stick around, they are likely to build centrist voting records between now and 2010.
