A headline on the MSNBC news aggregator on the lower left sidebar announces, very concerned: Not All Democrats Going For Obama. Among those Democrats who are, at best, sitting on the fence and, at worst, spreading right-wing talking points about the Democratic presumptive nominee, are Blue Dogs Rep. Jim Marshall of Georgia and Rep. Dan Boren of Oklahoma.

Not surprisingly, the RNC has jumped on their reluctance to get behind Obama (Marc Ambinder excerpts the memo) but as Ambinder rightly wonders:

Just asking: does the RNC really want to get into a debate over the number of partisans in each party who don't fully support their party's nominee?

From The Hill:

At least 14 Republican members of Congress have refused to endorse or publicly support Sen. John McCain for president, and more than a dozen others declined to answer whether they back the Arizona senator.

Many of the recalcitrant GOP members declined to detail their reasons for withholding support, but Rep. John Peterson (R-Pa.) expressed major concerns about McCain's energy policies and Rep. Walter Jones (R-N.C.) cited the Iraq war. [...]

Republican members who have not endorsed or publicly backed McCain include Sens. Chuck Hagel (Neb.) and Jeff Sessions (Ala.) and Reps. Jones, Peterson, John Doolittle (Calif.), Randy Forbes (Va.), Wayne Gilchrest (Md.), Virgil Goode (Va.), Tim Murphy (Pa.), Ron Paul (Texas), Ted Poe (Texas), Todd Tiahrt (Kan.), Dave Weldon (Fla.) and Frank Wolf (Va.). [Wolf contacted The Hill following publication of the article to correct his staff's error. His staff had said he has "yet to endorse McCain" and did not return follow-up phone calls this week].

Despite the fact that the MSNBC article leads with the Democrats divided meme (gee, what a shocker), it too acknowledges the reality of McCain's difficulty among his party's electeds:

McCain has his own issues in his party. Many conservatives opposed the four-term senator, who has worked with Democrats and strayed from GOP orthodoxy on some issues, before he sealed the GOP nomination in February. Many still express reservations about him as the party leader.

As The Hill notes:

It is not unusual for certain factions of the Democratic and Republican parties not to embrace their respective candidates for president...While some conservative Democrats have yet to endorse Obama and didn't back Sen. John Kerry (D-Mass.) in 2004, there are both centrist and conservative Republicans representing various parts of the country who are not embracing McCain.

But, you see, the difference is this: while for Barack Obama, the inability to consolidate his entire party behind him is a sign of weakness, for John McCain, it's excellent news!

In some ways, the lukewarm backing of some lawmakers could be a blessing, because congressional approval ratings are at an all-time low. And McCain himself has touted his independence, proudly pointing out that he has at times upset some of his Republican colleagues in Washington.

McCain campaign spokesman Tucker Bounds said, "John McCain has strong support among Republicans and even some others in the Congress for taking principled stands. While his support is rock solid, it also shouldn't be a surprise that Sen. McCain's bold record of independence on the issues isn't appreciated by every single Republican on Capitol Hill."
