It's that simple.
What is "the vital center"? Broder never tells us. Is it the large majority of the American people who favor a public option on health care? Is it the large majority who has elected Barack Obama President in the belief that he really was different, that he was a leader, that change we could believe in would come? Is the vital center the 60% and more of the American people who detested George W. Bush and the Republicans so much they stripped the party of any power in 2006 and 2008?
I have defended the bill and the process that led to it, and the President's role in that process, throughout the entire health care reform debate. That job has been easier because the right went off the deep end this summer with the Tea Party/Birther movement, while the left showed a surprising lack of sympathy for the limits of Presidential power and influence. The former, for some reason, think Obama is a fledgling dictator, while the latter want him to be and decry his relative silence during much of the debate in Congress.
While the health care debate, for all the crazies and ignorant folk on the extremes seemed to dominate in the press, was actually an important civics lesson for those ignoring the screeching and paying attention to the details, we have ended up with the President battered, the Democratic base turning away, in particular, from the Congressional party, and the prospects of financial industry regulation far dimmer than they might have been. If Obama shows the same inability to enter the debate at strategic points, and display a willingness to act in support of legislative measures he supports (as he did with the public option), my guess is the "vital center" will not be the Democratic Party's main concern going in to next autumn's elections, but the liberals, activists, and particularly bloggers who make up the activist and publicist base of the part who may just vote with their butts.
Broder's political instincts have been bad for years; he famously wrote a column in 2007 in which he predicted that then-Pres. Bush, whose approval ratings had not been above 40% since the previous summer, was "poised for a comeback". He seemed oblivious to the palpable public anger at George W. Bush in particular and the Republican Party in general for its gross malfeasance while in power. He lectured Democrats not to be too liberal, to be Republicans while they governed (which, if the example had been followed, would have meant not doing much, and what they did do they did very badly), and lamenting the passing of an old guard that had a record of corruption and maladministration little matched in American history.
I think it safe to say the Democrats can ignore the advice of David Broder. Indeed, like Bill Kristol, a safe bet would be to do the opposite; Kristol is the only pundit operating today with a worse record of advice and prediction than Broder. What they cannot do is ignore the rising tide of frustration and even anger among the Democratic base at the Congressional, particularly Senate, Democrats for the way they handled health care reform. If this is the way Harry Reid's tenure as majority leader is to continue, it might be wise to consider getting more and better Democrats in power, so that a change of leadership can come.
Don't listen to Bill Daley. Don't listen to David Broder. Listen to the people who actually voted for the Party and what they want in their elected representatives, what policies they want. That's the key to victory. No one elected either one of these folks to positions of authority. They can be ignored easily enough.
