Even though he's been a featured speaker at the Republican National Convention, Democrat-turned-independent Senator Joe Lieberman is still shelling out big money to help Democratic Senate candidates.

The Connecticut senator gave $100,000 to the Democratic Senatorial Campaign Committee last month. The move is a sign that he may be trying to hedge his bets this election season and hang onto his Senate committee chairmanship. Lieberman also gave $15,000 to the DSSC in March.

The 66-year-old Lieberman has angered many Democrats with his strong support for the Iraq war and for his longtime pal, John McCain.

There's speculation that if Democrats add to their 51-49 Senate majority this fall, they could seek payback by stripping Lieberman of his chairmanship of the Homeland Security and Governmental Affairs Committee.
