There was minimal rancor yesterday over House and Senate changes to President Obama's budget proposal. In fact, there was almost no rancor at all. Instead, the administration and Harry Reid and conservative Democrats in the Senate seemed all too thrilled with one another.

That will please some liberal grassroots organizations, and should be of particular interest to a campaign called Rebuild and Renew America Now, comprised of over 40 progressive interest groups aligned to usher Obama's budget through the Congress largely unmolested.

David Elliot, communications director for the group USAction, a member of the campaign, says the members (or as many as possible) convene for a daily 10:30 a.m. conference call to discuss budget issues and strategy.

Among their considerations is the crucial role Blue Dogs and conservative Democrats will play in the passage (or blockage) of Obama's agenda. For its part, USAction began airing ads in the districts of conservative Reps. Marion Berry, (D-AR), Allen Boyd, (D-FL), Charlie Melancon (D-LA), Bob Etheridge, (D-NC), and Chet Edwards (D-TX) urging them to "resist special interests and vote for [Obam's budget]. All of them serve on the House Budget Committee. Four of them officially belong to the Blue Dog Caucus.

Similarly, the labor-backed group Americans United for Change (also part of the Renew and Rebuild campaign) went live with ads today in 11 states and Washington D.C. to pressure critics like Kent Conrad and the newly christened Moderate Dems Working Group to support Obama's budget.

These efforts might seem bold and risky, but Elliot says there's little discord within the campaign itself over tactics and organizing. By contrast there is some disagreement within the ranks of a different (somewhat overlapping) umbrella group called Unity '09, which is also dedicated to moving Obama's agenda through Congess. Some Unity participants are much less suspicious of the Blue Dogs and their Senate peers, and have been heavily critical of efforts to pressure them.

As it happens, Conrad released his proposed tweaks to Obama's budget yesterday, and, despite making relatively few substantive changes, he seems to have won for now the support of many of its critics.
