Legislative absentee voters

Illinois politics is often anything but boring.  Yesterday it seems 18 legislators voted on legislation when they weren't on the floor - in violation of an apparently commonly ignored rule - and Governer wants to know who did the proxy voting.  I wouldn't mind knowing, too.

From the State Journal-Register:

Gov. Pat Quinn wants to know who cast votes for about 18 Illinois House members who weren't on the floor when the utility rate-hike legislation Quinn opposes passed.

Quinn on Thursday said nobody other than the House member should vote on such high-stakes legislation. He says the action should be investigated by the House, and he calls it a "violation of ethical conduct" [more].

Is it really too much to ask that our elected representatives personally represent us?
