Former Democratic senator and one-time presidential hopeful Bill Bradley on what the Democrats must do to renew themselves.

Some excerpts from his NYT commentary:

Before deciding what Democrats should do now, it's important to see what Republicans have done right over many years. When the Goldwater Republicans lost in 1964, they didn't try to become Democrats. They tried to figure out how to make their own ideas more appealing to the voters.

He then talked about the strategy developed for the Republicans by a guy named Lewis Powell, then a lawyer but someone who went on to service as a Supreme Court of the United States judge. Here's how it goes:

Big individual donors and large foundations - the Scaife family and Olin foundations, for instance - form the base of the pyramid. They finance conservative research centers like the Heritage Foundation, the Cato Institute and the Intercollegiate Studies Institute, entities that make up the second level of the pyramid.

The ideas these organizations develop are then pushed up to the third level of the pyramid - the political level. There, strategists like Karl Rove or Ralph Reed or Ken Mehlman take these new ideas and, through polling, focus groups and careful attention to Democratic attacks, convert them into language that will appeal to the broadest electorate. That language is sometimes in the form of an assault on Democrats and at other times in the form of advocacy for a new policy position. The development process can take years. And then there's the fourth level of the pyramid: the partisan news media. Conservative commentators and networks spread these finely honed ideas.

At the very top of the pyramid you'll find the president. Because the pyramid is stable, all you have to do is put a different top on it and it works fine.

It is not quite the "right wing conspiracy" that Hillary Clinton described, but it is an impressive organization built consciously, carefully and single-mindedly.

The problem with the Democrats, he says, is the party's structure is inverted. Everything rests on the presidential candidate. There is no funding base comparable to the Republicans.

There is no clearly identifiable funding base for Democratic policy organizations, and in the frantic campaign rush there is no time for patient, long-term development of new ideas or of new ways to sell old ideas. Campaigns don't start thinking about a Democratic brand until halfway through the election year, by which time winning the daily news cycle takes precedence over building a consistent message. The closest that Democrats get to a brand is a catchy slogan. ...

Bradley said part of the problem is the party is still dazzled by the glare of John F. Kennedy. But as Bradley notes, Bill Clinton cut a very charismatic figure, yet there were fewer Democrats overall at the end of his presidency than there were when they started.

If Democrats are serious about preparing for the next election or the next election after that, some influential Democrats will have to resist entrusting their dreams to individual candidates and instead make a commitment to build a stable pyramid from the base up. It will take at least a decade's commitment, and it won't come cheap. But there really is no other choice.
