Today, we learned that Media Matters might air an anti-Lou Dobbs ad during Dobbs's show on CNN; Sen. Arlen Specter (D-PA) and Health and Human Services Secretary Kathleen Sebelius got booed loudly at a town-hall in Philadelphia; the White House has decided to cast health insurers as the enemy; a liberal group followed suit with a TV ad; the industry's top lobbyist says insurers won't take the bait; the national debt grew a trillion dollars in 180 days; and Pollster.com has charts galore on GOP 2012ers.

We also contemplated Dan Bogden's journey from fired U.S. attorney to re-nominated U.S. attorney; whether the Sept. 15 deadline for bipartisan Senate health care negotiations will hold; whether advertising is journalism's biggest problem; killing cash for clunkers; and whether Dems are in for an August slaughter.

Tomorrow: it's President Obama's birthday; Democratic senators will meet at the White House; and the Department of Homeland Security, the Secret Service, and CyberScience Laboratory hold a Global Cyber Security Conference.
