Last Straw from LIEberman

It appears that Joe Lieberman's plan to address the GOP convention in St.Paul this summer is the final straw for Senate Democrats. Well, that and the fact that they'll likely pick up enough seats to make him fully disposable for the first time since the 2006 mid terms:

Despite assurances to the contrary from Senate Majority Leader Harry Reid, Democratic insiders are certain Sen. Joseph Lieberman next year will be kicked out of the party's caucus and lose his Senate chairmanship if he addresses the Republican National Convention in St. Paul, Minn., as planned.

Lieberman's Democratic colleagues willing to accept his support of Sen. John McCain for president consider speaking to the GOP convention as the last straw. Lieberman was re-elected from Connecticut as an independent in 2006 after losing the Democratic nomination because of his support for the Iraq war.

After his 2006 election, the Senate Democratic leadership agreed to give Lieberman the Homeland Security Committee chairmanship if he provided the decisive vote to make the Democrats a 51 to 49 Senate majority. However, with additional Democratic senators likely to be elected this year, that agreement is expected to be null and void in the new Congress.
