In 2004, then-Democratic Sen. Zell Miller (GA) threw his support behind President Bush with an over-the-top speech attacking Sen. John Kerry (D-MA) at the Republican National Convention. Earlier this week, Miller continued his assault on liberalism while campaigning for Sen. Saxby Chambliss (R-GA). “Saxby could well be the last man standing between a far-left liberal agenda sailing through the United States Senate,” said Miller. The National Republican Senatorial Committee released a web-only ad yesterday featuring Miller’s comments. Watch it:

Though Miller is now stoking fears of a filibuster-proof Democratic majority in the Senate, the Atlanta Constitution Journal notes that “as a senator, when Republicans controlled the chamber, Miller declared reliance on a 60-member cloture vote in the Senate, needed to shut off debate, to be undemocratic.”

After nearly one year of negotiations, the Iraqi cabinet voted “overwhelmingly” Sunday to approve a security agreement requiring “coalition forces to withdraw from Iraqi cities and towns by the summer of 2009 and from the country by the end of 2011,” the New York Times reports. “An earlier version had language giving some flexibility to that deadline…but the Iraqis managed to have the deadline set in stone, a significant negotiating victory.” Earlier this month, the Times reported that Barack Obama’s victory spurred the Iraqi political process toward finalizing a withdrawal agreement. In the words of one Iraqi politician:

“Before, the Iraqis were thinking that if they sign the pact, there will be no respect for the schedule of troop withdrawal by Dec. 31, 2011,” said Hadi al-Ameri, a powerful member of the Islamic Supreme Council of Iraq, a major Shiite party. “If Republicans were still there, there would be no respect for this timetable. This is a positive step to have the same theory about the timetable as Mr. Obama.”

After Sen. Joe Lieberman (I-CT) spoke at the Republican National Convention this summer, Sen. Byron Dorgan (D-ND) expressed his frustration: “Everybody is just profoundly disappointed with what Joe did,” Dorgan said.

Today on Fox News Sunday, host Chris Wallace asked Dorgan whether he would vote on Tuesday to allow Lieberman remain chairman of the Homeland Security Committee. Dorgan said he was “concerned” and “upset” over Lieberman’s behavior during the campaign, and suggested that Lieberman’s actions were unacceptable for a committee chairman:

As a chairman of one of our significant committees in the Senate, not just going off and supporting a presidential candidate of the other side but also criticizing the candidate on our side, and also involving himself in a couple of senate races on the other side. The question is, is that acceptable? The answer is no.

Watch it:

Sen. Jon Kyl (R-AZ) said the Republicans would embrace Lieberman into their caucus “with open arms” in an effort to boost the party’s Senate numbers. Kyl heralded Lieberman has “a great American” and said his party would “love to have him.” Dorgan emphasized that expelling Lieberman from the entire Democratic caucus is “not on the table;” the Tuesday vote will pertain only to his position as chairman.

So far, Sens. Patrick Leahy (D-VT) and Bernie Sanders (I-VT) are the only senators to have explicitly called for Lieberman to lose his chairmanship.
