The Dems are controlling more than just the White House and Congress. They’re also collectively winning the battle for traffic among political sites. According to the latest comScore (NSDQ: SCOR) numbers, left-leaning sites attracted 6.4 million uniques in April, while the major blogs on the right 4.8 million. (See chart after the jump)

The right is not without some bragging rights. Individually, the right had one more site in comScore’s top 20 political blog sites than their left wing counterparts (nine to eight), and many of the conservative sites, like MichelleMalkin.com, had enormous growth, while liberal stalwarts like DailyKos and MyDD appeared to be dropping uniques year-over-year. However, since these are comScore numbers, websites are sure to disagree with the findings. TalkingPointsMemo, for example, tells me the 203,000 uniques that comScore assigned to them is way off; they claim to have had 1.4 million in April.

There was one main reason the liberal sites collectively came out ahead: Huffington Post’s dominant 5.6 million uniques, which dwarfs the number-two site Drudge Report’s 1.7 million monthly visitors. That’s a gap that conservative reporter and TV pundit Tucker Carlson is angling to fill with his new political news site The Daily Caller, which The Hill described as a right-wing version of HuffPo. For his part, Carlson told a conference that he plans to position it as a “general-interest newspaper-format style site” that will focus on the Obama Administration. I spoke briefly to Carlson today about the project, which he said is scheduled to launch in three weeks. He declined to offer any further details on whether the site would be ad supported or where the investment money was coming from.
