Chart comparing how Hillary, Obama and Lieberman voted on Iraq-related issues.

Hillary and Obama voted exactly the same on every vote but one, on whether to confirm General Casey to be Army Chief of Staff. Hillary voted against him, Obama and Lieberman voted for him.

On every other vote Hillary and Obama have the same opinion.

Lieberman, however, voted on the opposite side eleven times, and where Obama missed one vote and Hillary missed none, Holy Joe missed six.

The chart is very revealing: It demonstrates Lieberman's increasing trend of voting with the GOP on everything from detainee treatment, to military commissions, to regime change in Iran, to resolutions on Iraq, to the recently-passed timetable for withdrawal, and even procedural motions on whether or not to debate the subject at all.

Another interesting pattern: Lieberman's breaking ranks with Dems has steadily grown much more frequent over time as the war progressed — and especially after his 2006 reelection as an Independent. Since then he's voted with the GOP on war-related questions far more frequently than he did in the past.
