Democratic loyalists are fighting with conservative Democrats_over the airwaves.

MoveOn.org, considered sympathetic to liberal Democratic causes, plans to run radio ads beginning Wednesday aimed at pressuring three party House of Representatives members. Reps. John Barrow, D-Ga., Jim Matheson, D-Utah and Charlie Melancon, D-La., were among five Democrast who Friday voted against a health care plan authored by House Democratic leaders.

The plan won House Energy and Commerce Committee approval, as 31 Democrats voted yes. All committee Republicans and the five Democrats voted no. Two other House committees have also passed health care overhaul legislation, and House Democratic leaders will merge the three versions into one bill. They hope for a full House vote by mid-September.

And MoveOn.org wants dissident Democrats to know they should think about their votes.

“Americans cannot afford to wait any longer for health care reform. The Blue Dogs who voted against the health care bill will have to go home and explain why they sided with insurance industry instead of voting to fix our broken health care system,” said Justin Ruben, Executive Director of MoveOn.org. “MoveOn’s 5 million members expect the Democrats in Congress to deliver on the promise of change that got them elected."

The ad starts by saying that in the local congressional district, "a patient lost insurance coverage (today) for medical care she needs," and "hospital bills will eat up another family's savings."

"Instead of helping (local) families get more affordable, quality health care," the ad says, "Congressman (Barrow/Matheson/Melancon) sided with the special interests and insurance companies."

Republicans want you to know that, in their view, President Barack Obama's not a doctor, but he plays one on TV.

The House GOP Monday unveiled a new video juxtaposing some recent Obama comments with an old 1980s footage from the ad where an actor explained how he was a doctor on TV only.

House Republican Leader John Boehner drove home the point in a statement:"  This is a lighthearted video, but it underscores a serious point that Congressional Democrats are going to hear throughout August as they travel outside of Washington: Americans want lower health care costs – not a trillion-dollar government takeover of health care that increases costs and lets Washington bureaucrats make decisions that should be made by doctors and patients.”

Here's something rarely seen at the Capitol: A committee chairman threatening to bypass his own committee in order to get a health care vote.

House Energy and Commerce Committee Chairman Henry Waxman, D-Calif., has been trying all week to find consensus among Democrats. Moderates have balked at other Democrats' efforts, saying they want more changes that could include more spending cuts.

If some agreement is not reached soon, Waxman told reporters Friday, "We're going to have to look at perhaps bypassing the committee because we've got to get moving on this legislation. I hope we don't come to that conclusion."

One of his fears is that should the seven committee Democratic moderates join Republicans, they would effectively control the committee, and Waxman said, "We're not going to let them empower the Republicans to control the committee."

The House of Representatives is scheduled to leave for its summer recess July 31. Democratic talks were to continue Friday afternoon.

It's going to be up to the voters in 2010 to decide how they view Democratic centrist congressmen, and both Democrats and Republicans are pushing hard to make sure that voter understands the nature of the ... ahem ... beast.

Blue Dogs are 51 House of Representatives Democrats, moderates who consider themselves more fiscally conservative than party leaders. But most also have voted for recent Democratic-authored budgets that increase spending well above the rate of inflation.

As a result, Republicans are taking aim, and starting Wednesday plan to run ads against moderates they see as vulnerable. A sample of the one planned against Arkansas' Marion Berry, a congressman since 1997:

"In Arkansas," the announcer says, "Marion Berry calls himself a BLUE DOG. A Blue Dog DEMOCRAT, that is. Berry claims he’s conservative on budgets and spending ... but this year in Washington, Marion Berry’s not voting like a Blue Dog ... He’s voting like a Lap Dog."

It goes on to tie Berry to President Barack Obama and House Speaker Nancy Pelosi. Blue Dogs have countered that they helped get spending levels down from what Obama sought - they did help get some cuts in the budget resolution approved recently - and their numbers alone give them enough clout to make members of both parties think hard before spending excessively.

The Blue Dog coalition has 51 members. Democrats control 256 House seats and 218 constitute a majority.
