Can President Obama Organize America?

To demand action from Congress — on healthcare, energy independence and the stimulus package — the President's using the bully pulpit. That's business as usual.  But Obama's extraordinary campaign apparatus may give him a new kind of political weapon. With e-mail, social networking sites and text messaging, he can directly reach some 13 million Americans who supported his presidential campaign. The call has gone out for neighborhood meetings this weekend to discuss his agenda and how to get it approved on Capitol Hill. Will the "online army" that transformed campaigning change government too?  What's the risk of backlash from Congress and from the "army" itself?
