Last night Markos described Democratic losses as "a base problem" and said:

Tonight proved conclusively that we're not going to turn out just because you have a (D) next to your name, or because Obama tells us to. We'll turn out if we feel it's worth our time and effort to vote, and we'll work hard to make sure others turn out if you inspire us with bold and decisive action. The choice is yours. Give us a reason to vote for you, or we sit home. And you aren't going to make up the margins with conservative voters. They already know exactly who they're voting for, and it ain't you.

And today, Think Progress expands on that point with a look at how Creigh Deeds failed to run as a progressive ... and failed miserably:

NOT PROGRESSIVE ON CLIMATE: By the end of his campaign, Deeds was running ads attacking Obama’s clean energy agenda, saying Obama’s “cap and trade bill” would “hurt the people of Virginia.” Other ads carried the same message: “Creigh Deeds says no to any new energy taxes from Washington.” Instead of disputing his Republican opponent’s false attacks on climate legislation, Deeds amplified them. Deeds chose to run away from his past record on environment and climate issues. [...]

[...] NOT PROGRESSIVE ON HEALTH CARE: During the final gubernatorial debate, Deeds stressed that health reform must “reduce costs so more people can afford insurance” and “increase coverage,” but argued that creating the option of a public health care plan “isn’t required.” “I don’t think the public option is necessary in any plan...I would certainly consider opting out if that were available to Virginia,” he said.

[...] NOT PROGRESSIVE ON LABOR ISSUES: “When I’m governor, you won’t just have a friend in Richmond — you’ll have a partner,” Deeds told union supporters in October, 2008. However, despite support from SEIU and the Teamsters, Deeds then proceeded to campaign on an anti-labor platform. He opposed the Employee Free Choice Act (EFCA) — which would have created a fairer path toward unionization for workers — saying it would “put us at a competitive disadvantage” and reasserting the false right-wing claim that EFCA would eliminate the secret ballot in union elections.

[...] NOT PROGRESSIVE ON IMMIGRATION REFORM: More than one in ten Virginians are immigrants. The Immigration Policy Center also points out that Latinos comprised 2.0% (or 74,000) of Virginia voters in the 2008 elections — enough to make a difference in a tight race. Creigh Deeds might regret repeatedly voting in favor of legislation that would hurt a large and growing part of his constituency.

And if you need further proof that running against progressive values is a losing proposition, consider this -- the Republican leadership, deeply concerned about the future of our party, are now urging Democrats to run to the center. Enough said.
