Hit Obama where it matters! Bush's legacy!

"... I think Republicans have sometimes settled for an intellectually lazy critique because, given how weak the opposing party's record is, that seems to have sufficed.
Not this time. Obama has serious national security weaknesses and a record that warrants critique, but it is immune to superficial sound bite attacks. Soft on protecting America? The SEALs bought Obama immunity on that one when they took down Bin Laden. Naïve about the Iranian threat? Candidate Obama was demonstrably naïve about Iran and governed that way for the first half of his term, but since then has talked tough and marshaled strong sanctions.
Even issues where he has made bigger mistakes, like the failure to secure an agreement for stay-behind forces in Iraq, he may not be as politically vulnerable because they have been popular mistakes. The Iraq case illustrates my larger point well. Obama's hands-off approach to Iraq merits criticism (and I have supplied some here, here, and here, but it is hard to present the argument in a fashion that is brief enough to engage but fair enough to withstand administration rebuttals). Thus, Obama may have been hands-off personally, but the administration was not; Vice-President Biden devoted considerable time to the Iraq file, and with Ambassador Crocker on the ground, the administration had a good team in place. Moreover, the lion's share of the blame for the failure rests with the Iraqi leadership. I think reasonable people can question the way Obama handled the Iraq file, but it requires a nuanced line to explain how the administration missed the mark. Offer a sloppy critique, and the administration and its allies in the media swat it down with "But Bush negotiated the withdrawal agreement" -- and all too often the discussion ends there.
The Obama team's rare invocation of a Bush policy in the defense suggests two fruitful lines of contrast that the Republican nominee should develop:
1. Obama's foreign policy successes have come when he has followed Bush policies; his failures have come when he has struck out on his own....
2. Obama has made relatively effective use of the tools and instruments of power that he inherited from his predecessor -- it raises the question, what new tools and instruments of power is Obama bequeathing to his successor?..."
