The Obama campaign knows full well that it's to his advantage if he's seen engaging presumptive GOP nominee John McCain, as it signals to Dems that the GOP views him as the presumptive Dem nominee.

So it's noteworthy that Camp Obama moved to engage McCain on two fronts this morning. On campaign finance, Obama spokesperson Bill Burton hit McCain for hypocrisy, and on a conference call with reporters moments ago, Obama foreign policy adviser Susan Rice went after McCain for his claim yesterday that Obama "wants to bomb Pakistan without talking to the Pakistanis." As Rice noted, this is -- how to put this politely -- complete nonsense.

Anyway, the sight of Obama increasingly engaging McCain is the last thing Camp Hillary needs right now.

Late Update: For much, much more on Obama's foreign policy conference call, read this post from Matthew Yglesias.
