A legitimate policy debate has arisen between the two Democratic presidential candidates this week: whether or not to support John McCain's plan for a gas tax holiday this summer. While Hillary Rodham Clinton has jumped on the Straight Talk Express for this particular issue, Barack Obama is the only candidate to reject the proposal, calling it a "Washington gimmick."

Today the Obama camp is out with a new TV ad, a response to Clinton's "Trouble" ad that launched yesterday, in which she jabs Obama for his opposition to her foreclosure freeze and the gas tax plan. Showing footage of a stump speech given by Obama in North Carolina this week, "Truth" suggests that the McCain/Clinton proposal is "typical of how Washington works" and a "short-term quick fix," while he is the candidate who will bring long-term change to the country's oil addiction.

"I'm here to tell you the truth," Obama declares in the ad, airing in Indiana and North Carolina. "We could suspend the gas tax for six months," but individuals would only save about $25, "or half a tank of gas." He proposes "going after oil companies" for "price gouging," while focusing on the larger problem of the nation's overall oil consumption. "That's the real honest answer to how we're going to solve this problem," not political posturing, he says.

Obama is getting credit from some commentators for resisting what many economists and legislators agree is a flawed strategy, with the Washington Post praising his "political courage" in saying no to the gas tax holiday. But Clinton is trying to use the issue to portray Obama as out of touch with voters who are hurting from rising fuel and food costs.

Meanwhile, Obama is also fighting back against a pro-Clinton group, the American Leadership Project, which is pouring $1 million into an anti-Obama ad campaign in the Hoosier State. The Obama camp filed a complaint with the Federal Election Commission this week, alleging that the group is violating the law by specifically targeting Obama in their TV ads (as a 527, the group is supposed to be limited to issue advocacy) and comparing ALP to the "Swift Boat" group that attacked John Kerry in the 2004 election. The FEC is short-staffed due to a standoff between congressional Democrats and the Bush administration, but Obama chief counsel Bob Bauer requested that the body refer the ALP case to the Justice Department if it is unable to pursue an investigation.
