Though President Barack Obama once promised to “put on a comfortable pair of shoes myself, I’ll will walk on that picket line” when labor unions were under threat, his former campaign and government staffers are eagerly joining union busting groups for fun and profit.

First there was Obama’s former press secretary Robert Gibbs and former campaign spokesman Ben LaBolt who signed on to campaign for busting teachers unions in favor of privatizing public education, and now former Obama campaign strategist David Plouffe has joined the board of private taxi service Uber.

Uber has been waging a fierce campaign to destroy taxi unions in cities in order to take over the personal transportation market. Plouffe was likely brought in to help balance the political image of the company after founder Travis Kalanick made his devotion to Ayn Rand and her beliefs known.

Enter Plouffe, now in charge of “UBER THE CANDIDATE,” as the company’s chief executive, Travis Kalanick put it in a blog post. He’s a guy who knows how to manage data. He’s a guy who knows how to run a liberal ground game. He’s a guy who knows labor politics and wedge issues and what fires people up. And he’s a guy who knows how to use social media to activate liberal urbanites — liberal urbanites who might not be terribly involved in the local political process but can make their voices awfully loud when they want to…

Uber “poses a threat to some, and I’ve watched as the taxi industry cartel has tried to stand in the way of technology and big change,”Plouffe wrote. “Ultimately, that approach is unwinnable. But I look forward to doing what I can right now to ensure drivers and riders are not denied their opportunity for choice in transportation.”

Though David Plouffe is not the only former Team Obama alumni to help conservatives, as President Obama’s 2008 campaign manager, Jim Messina, went to work for the Conservative Party in the UK. Talk about change.

Why did the Obama campaign and presidency produce so many crass opportunists? Is it a result of a flawed message or a messenger who was more comfortable with a mercenary characteristic to his team? Maybe pragmatism was just a cover for self-serving cynicism, it usually is.

The willingness of former staffers for President Obama to offer themselves up to the highest bidder is getting so shameless and obvious that even the Democratic partisan press is starting to wonder if Team Obama produces sellouts.

Will President Obama put on his walking shoes to march against his former staff?
