I don't know much about Senator Lincoln Chafee, other than he's a Republican and he's from Rhode Island. I suppose I know in a roundabout way, from following politics closely that he's a moderate--something increasingly rare on the Republican side of the aisle.
In a surprising decision, he appears ready to buck his party and vote against the Alito nomination, lending some possibility to a filibuster.
Speaking of moderate Republicans (they used to be called, "Rockefeller Republicans," btw), my own Senator, Olympia Snowe, is also firmly in the camp of moderation. I always chuckle about how the conservative hard-ons in my own state get apoplectic about Snowe, calling her a RINO (Republican In Name Only) and that she ought to leave the party, ala Jim Jeffords (I-Vt). Then, she goes out every election and wins 70 percent of the vote. I guess these knuckle-draggers don't know the voters as well as they think they do.
Well, you know the drill. If you are a Mainer, call her office (202-224-1946) and urge that she vote against confirmation of Alito and seeing the Court hijacked by idealogues. Oh, and be nice--her staff are surely being bombarded today.
If you are in a state with a Senator who might be termed a moderate, a call to their staff wouldn't be a bad idea.
Since Maine has two of the four (in addition to Snowe, Maine's Susan Collins is also termed a moderate), your job is easy. Collins office can be reached at 202-224-2523.
Of the remaining two, I've mentioned Rhode Island's Chafee. That leaves only solitary John McCain (R-Az).
Commence dialing, loyal denizens of Maine and Arizona.
