I think so.
This does not mean that Obama is Saul Alinsky's ideological clone -- far from it. It does means that he's one of the few prominent Democratic politicians who not only understands Alinsky and his methods, but knows how to use them in a political campaign in the modern era.
I started out the 2008 election cycle backing John Edwards, in part because of his stances and in part because early polling showed that he'd do better in the general election against John McCain than either Hillary Clinton or Barack Obama. Unfortunately, Edwards lacked both the machine backing of Hillary Clinton and the amazing organizational skills of Obama. Furthermore, his populist program was unpopular with the millionaire talking heads whose paychecks come from conservative billionaire media moguls, and so he was singled out to be destroyed from the get-go. Edwards is in fact so hated by the GOP/Media Complex that months after his final primary defeat and presumed retirement from politics, if not public life, they went out of their way to dredge up a story about an old affair of his, just to make sure he could never come back. (Adultery, like so many other sins in America, is only allowed if you're a Republican. Just ask Giuliani and McCain and Bob Dole and Newt Gingrich, for starters.)
So, with Edwards out, I decided to support Obama, mainly because the Rasmussen and Gallup polling done in the fall and winter of 2007, as well as early 2008, showed that he was more likely than Senator Clinton to beat John McCain -- who, it was clear from the start, would be the GOP's nominee. I was worried that he might not be able to surmount the racism that I knew would keep the election closer than it deserved to be, but I suspected that it would be easier for him to win than it would be for Hillary, despite everything.
It turns out that Obama may well be the most skilled politician since Lyndon Johnson held court in the Senate. This is in part because of his taking the fine and nearly lost art of political organizing and bringing it into the 21st century.
