Most people who run for office don't want to be issue candidates. They want to win, not move the conversation. John Edwards wanted to win but he exited as an issue candidate.
Paul Krugman bids Edwards a fond farewell by explaining how Edwards actually did move the conversation. All that effort and sacrifice had good effects on the Democratic Party. Now maybe, it will have good effects on America, indirect though they may be.
Krugman does miss with this:
It’s true that Mr. Obama has tried to work some populist themes into his campaign, but he apparently isn’t all that convincing: the working-class voters Mr. Edwards attracted have tended to favor Mrs. Clinton over Mr. Obama.This should have been true. Edwards was the candidate who gave the working class a seat at the table, and he did get some union support because of it. But the truth is that Edwards was more popular with liberal, educated, relatively affluent white guys like me, and there just aren't enough of us to win any vote.
