Sen. Joe Lieberman (I-CT) has played an outsize role at national conventions for both parties for years. He was Al Gore’s VP pick for Democrats in 2000, and he spoke at the Republican convention in 2008 in support of John McCain over Barack Obama. This time around, though, neither party wants him to show up at their convention. From The Hill:

Sen. Joe Lieberman has not been invited to either the Democratic or the Republican presidential convention this year, a major snub for a lawmaker who played prominent convention roles in the past.

Lieberman (Conn.), a self-described Independent Democrat, still has many powerful friends on both sides of the aisle. This week he will manage the cybersecurity bill on the Senate floor, one of the few pieces of legislation with a chance to pass Congress before the election.

But when Democrats and Republicans gather in Charlotte, N.C., and Tampa, Fla., later this summer, Lieberman will receive less homage than a local councilman. He will be left out of the festivities altogether.

This snub really couldn’t have happened to a more deserving individual. Whether it was him working to make the Democratic party more corporatist, disloyalty to his party’s nominee, his support of a destructively bad foreign policy or simply working to make health care policy worse purely for spite, Joe Lieberman has finally managed to make his brand something neither party wants to be associated with.

While simply not being invited to the fancy parties would be a rather small punishment to a regular person, Joe Lieberman does seem like the type of guy who takes this stuff very personally. It is another sign Lieberman is finally leaving office on a low note, too unpopular to run for re-election and unwanted by both major parties.
