Senator Lieberman has less and less to recommend him, now that he's become the gaffe-minder of John McCain and what little Democratic credibility he had is quite shredded. But he did sponser a climate control bill, so at least on that front he's in the right place
Which makes him a target; from msnbc.com,this story:
A conservative, free-market advocacy group will begin airing ads this week pressing Senate Republicans and Democrats to vote against a bill that aims to reduce greenhouse gas emissions.
The Club for Growth wants to scuttle a bill by Sens. Joseph Lieberman, an independent from Connecticut, and John Warner, R-Va., that the Senate is scheduled to begin debating next month. Despite the ad campaign, the bill seems to lack the votes needed to overcome a filibuster.
With $250,000 in radio and television spots, the Club for Growth is targeting Republican Sens. Elizabeth Dole of North Carolina and Lamar Alexander of Tennessee, and Democratic Sens. Robert Byrd and Jay Rockefeller of West Virginia and Max Baucus and Jon Tester of Montana. Dole, a co-sponsor of the bill, as well as Alexander, Baucus and Rockefeller face re-election this year.
Club for Growth President Pat Toomey, a former Republican congressman form Pennsylvania, called the legislation a "massive redistribution of wealth.''
Some might say that is one if its strengths.
Not that the Club for Growth likes McCain, either, again because he has a relatively reasonable environmental plank. "The fundamentals that Senator McCain seems to support are badly misguided,'' Toomey said.
