The president's third prime-time address/press conference tonight was basically a call to chill: the president said solving the economic crisis will "take patience," that "we're all in this together" and that we can't afford to "demonize every investor or entrepreneur who seeks to make a profit."
Also, he's only been in office 60 days, and the country is "moving in the right direction."
Obama's PR strategy, with which this press conference fits perfectly, has been to be almost ubiquitous on television; Ad Age summarized it (to paraphrase) as basically "there's no such thing as overexposure, because everyone watches different channels now and/or is apathetic."
If the intended effect of the blitz is to calm everyone down, as it seems to be, a nice side benefit of the exposure is refreshing Obama's political capital. With a bailout, budget and health-care plan to get through Congress, the president will need it.
