The Iowa Independent caught this quote from Sen. Tom Harkin (D-Iowa), talking about Sen. Joe Lieberman’s (I-Conn.) recent threat to join a GOP filibuster of a health care bill that includes a public health insurance plan.

“[Lieberman] still wants to be a part of the Democratic Party although he is a registered independent. He wants to caucus with us and, of course, he enjoys his chairmanship of the [Homeland Security] committee because of the indulgence of the Democratic Caucus. So, I’m sure all of those things will cross his mind before the final vote.”

That’s the first time I’ve heard a congressional Democrat bring up Lieberman’s chairmanship as something the Connecticut senator might lose if he were to vote against a Democratic health bill.
