If President Obama happened to glance at “The Rachel Maddow Show” last Monday, he might have winced.

Ms. Maddow pretended to celebrate the passage of a health care overhaul bill in the House, calling it “potentially a huge generational win for the Democratic Party”  but then halted the triumphant music and called it an “electoral defeat.”

The Stupak amendment, she said, was “the biggest restriction on abortion rights in a generation.” Then she wondered aloud about the consequences for Democrats “if they don’t get women or anybody who’s pro-choice to ever vote for them again.” She returned to the subject the next four evenings in a row.

This is how it looks to have a television network pressuring President Obama from the left.

While much attention has been paid to the feud between the Fox News Channel and the White House, the Obama administration is now facing criticism of a different sort from Ms. Maddow, Keith Olbermann and other progressive hosts on MSNBC, who are using their nightly news-and-views-casts to measure what she calls “the distance between Obama’s rhetoric and his actions.”
