While the Clinton and McCain campaigns attempt to paint Barack Obama as a cultural elitist, he's doing his darndest to highlight whose policies are most "out of touch" with the needs and concerns of America's working class.

From a speech today at an Alliance for American Manufacturers event in Pittsburgh:

You know, there’s been a lot of talk in this campaign lately about who’s “in touch” with the workers of Pennsylvania. Senator Clinton and Senator McCain are singing from the same hymn book, saying that I'm “out of touch” – an “elitist” – because I said a lot of folks are bitter about their economic circumstances.

Now it may be that I chose my words badly. It wasn't the first time and it won't be the last. But when I hear my opponents, both of whom have spent decades in Washington, saying I'm out of touch, it's time to cut through their rhetoric and look at the reality ...

Now, you can have a debate about whether my position is right or wrong. But here’s what you can’t do. You can’t spend the better part of two decades campaigning for NAFTA and PNTR for China, and then come here to Pennsylvania, and tell the steelworkers you’ve been with them all along. You can't say you are opposed to the Columbia Trade deal, while your key strategist is working for the Columbian government to get the deal passed.

That’s not respect. That’s just more of the same old Washington politics. And we can’t afford more of the same.

It's a point he's been hammering since the Huffington Post reported on his recent comment at a San Francisco fundraiser.

(More after the jump ...)

Here he is again on Friday:

“Out of touch? Out of touch? I mean, John McCain—it took him three tries to finally figure out that the home foreclosure crisis was a problem and to come up with a plan for it, and he’s saying I’m out of touch? Senator Clinton voted for a credit card-sponsored bankruptcy bill that made it harder for people to get out of debt after taking money from the financial services companies, and she says I’m out of touch? No, I’m in touch. I know exactly what’s going on. I know what’s going on in Pennsylvania. I know what’s going on in Indiana. I know what’s going on in Illinois. People are fed-up. They’re angry and they’re frustrated and they’re bitter. And they want to see a change in Washington and that’s why I’m running for President of the United States of America.”

Whether the controversy resonates is yet to be seen. The latest polling numbers from Pennsylvania suggest Obama may take a hit. However, when Clinton brought up the issue at the Alliance for American Manufacturing event this morning, she was greeted with "groans," according to MSNBC.

Regardless, the crux of Obama's argument is a valid one. And his supposedly controversial statement -- widely accepted by many cultural critics -- changes nothing about the policies he would advocate as president. As Ezra Klein writes, "[W]e reporters have to cover it, of course, because it's Really Important, and matters more than the housing plans of all the candidates put together. But it matters in a completely self-referential way, it matters only because it matters, not because it means anything about Obama, or illuminates anything about his potential presidency."
