WASHINGTON--President Barack Obama's political army--his new nonprofit, Organizing for Action, spawned from his campaign--launched its first push on Friday, to bolster Obama's proposals for universal background checks for all gun purchasers.

The revamped OFA, with an office in Washington and soon to have one in Chicago, is targeting 80 congressional districts with a variety of free and paid on-line social media, grassroots and traditional political activities such as petitions and candle light vigils.

Of note: The OFA, on its inaugural thrust, is being very careful, asking supporters to organize on the least controversial proposal in the Obama package of items to curb gun violence.
