The Note's Sneak Peek:

August 1, 2007— -- When Barack Obama asserted himself on foreign policy last week, saying he would meet with leaders of rogue nations, Hillary Clinton smacked down that position as "irresponsible and frankly naïve"

But Obama's announcement today that he would use military force if necessary to hunt down terrorists in Pakistan drew nary a peep from the Clinton campaign.

Both Clinton and Obama will be in DC Thursday tending to Senate duties.

John Edwards responded to Obama on Tuesday with a statement saying that "maximum diplomatic and economic pressure" on states like Pakistan and Saudi Arabia should be the first option while adding that he would not hesitate to use force against terrorists.

Joe Biden congratulated "Johnny-Come-Lately" Obama for adopting his own views on fighting al Qaeda in Afghanistan and Pakistan. "Much of what Senator Obama has proposed Senator Biden has already initiated or accomplished," the campaign said in a statement, reports ABC News' Brian Wheeler. LINK

The White House asserted its own policy of respecting the sovereignty of Pakistan is the correct one -- but left it at that.

Thursday it's Michelle Obama's turn at the campaign podium. The Illinois Senator's spouse will make her first formal policy remarks at 11am in front of the Iowa State Education Association conference in Storm Lake.

Michelle Obama largely will reiterate her husband's stance on education, but this is the fist time she will address specifics such as "No Child Left Behind," ABC News' Sunlen Miller reports. Mrs. Obama then heads to Des Moines for a meeting with "African Americans for Obama" at 5 pm.

Uncertainty hangs over the 10:00am ET Senate Judiciary Committee hearing Thursday on the U.S. Attorney investigation and there are conflicting reports about whether Scott Jennings, Karl Rove's deputy, will make an appearance, ABC News' Jason Ryan reports. Tony Snow said today a Fred Fielding letter will explain Rove's status for the hearing, but it's unlikely the deputy chief of staff will be spotted on Capitol Hill.

Both Rove and Jennings were issued subpoenas to testify tomorrow. This all comes as the Department of Justice released another 40 pages of emails on the firings.
