MORNING READ

The attacks against Barack Obama continue to reverberate around the blogosphere Tuesday morning.

The Weekly Standard's Michael Goldfarb writes that it's been a bad week for the Democratic frontrunner, who has stumbled by making the "bitter" comment and is now seeing his poll numbers fall in Pennsylvania. Goldfarb suggests that Obama is suffering from overexposure, as he's running more television ads than his opponents. Clinton supporter Jeralyn at Talk Left finds that Obama was the one who attacked Clinton at the Philadelphia Jefferson-Jackson Dinner. Clinton, meanwhile, talked more about her own policies, an approach that Jeralyn found more effective. And Victor Davis Hanson at The Corner likens the presidential race to the one in 1952, when a war hero beat the "thinking-man's candidate."

Pushing back against Obama's critics, Arianna Huffington argues that John McCain can now go on vacation since Clinton is doing his bidding. Daily Kos's DHinMI takes issue with the suggestion by Clinton, the multi-millionaire wife of an ex-president, that Obama is "elitist" and is like former Democratic nominees Al Gore and Sen. John Kerry (D-Mass.).

But it's not just McCain and Clinton attacking Obama. MissLaura, another Kos blogger, finds Netroots nemesis Sen. Joe Lieberman (I-Conn.) telling a reporter that he sometimes finds Obama "far to the left" of "mainstream America." And Jonathan Singer at MyDD notes Rep. Geoff Davis's (R-Ky.) botched remark in which he referred to Obama as a "boy."

Shining a light on both parties' rhetoric in the election, Time's Michael Scherer takes issue with Republicans and Democrats for resorting to "truthiness" in their attacks instead of sticking to the truth, something that many expected campaigns would do in the age of Internet fact-checking.
