Do Lieberman and McCain have a new best bud?

Speaking of stuff in The Wall Street Journal today, Joe Lieberman had a good piece on the Opinion pages about the importance of the upcoming Tunisian elections.

You should read it all (if you can get past the pay wall), but what grabbed my easily-distracted attention was this:

Third, the U.S. should recognize that the foremost challenges for Tunisia’s new government will be economic, in spurring growth and reducing unemployment. While the U.S. cannot offer billions of dollars of direct aid, given our own economic challenges, there are other actions we can take. These include establishing a robust Millennium Challenge Corporation compact with Tunisia and expanding the European Bank for Reconstruction and Development to operate there. Congress should also pass legislation, which I co-sponsored with Sens. John Kerry and John McCain, to establish a Tunisian-American Enterprise Fund aimed at helping small and medium-sized businesses, and modeled after similar efforts in Central Europe following the fall of communism.

For the longest time, it was Lieberman, McCain and Lindsey Graham doing everything together, including road trips. Then, there was a sort of transitional trio when Lieberman, Graham and Kerry worked together on trying to push an actual, coherent, comprehensive energy policy for the country (one that looked pretty good from an Energy Party perspective).

Then, Graham took all kinds of horrific grief from the most hateful ideological extremists in his own party from having had any dealings with a Democrat, and pulled out of the deal — tragically, thereby collapsing it.

Now, it’s Lieberman, McCain and Kerry? Is Kerry the new, replacement member of the Three Amigos? Is he Ringo to Graham’s Pete Best?
