The Lieberman-Warner “Environmental Sell-out to REEELLY BEEG Corporate Polluters” bill got through its first markup in committee yesterday. Kate Shepard on Tapped today noted:

Yesterday afternoon, John Kerry held a conference call with bloggers that covered a range of topics, from international accords to probably the hottest domestic topic, the Lieberman-Warner bill, or “America’s Climate Security Act.”…Kerry seemed to think that worries about passing weaker legislation now and getting stuck with it are unfounded. We can pass a plan now and strengthen it later, he says, as support for action on climate change grows among citizens and businessfolk

.Just out of curiosity, can somebody provide examples of bills—legislation, yaknow?— which were regarded as too weak at their passage, and which were subsequently STRENGTHENED in the public interest—that is, their regulatory properties were INCREASED—later at the expense of the interests which assured their weakness in the first place?
