Rich Miller graciously gave permission to post this snippet from his subscriber-only daily fax of his thoughts re: the Blagojevich stem cell executive order yesterday:

Technically, the pro-life members can say that the money had no stated purpose until the governor issued his executive order to spend it. But this was undoubtedly a secret deal cut by three Dem leaders and, perhaps, one GOP leader and, as a result, has to be the most well-hidden appropriation we’ve seen in a long time. If I were one of those aforementioned Dems, I wouldn’t be very happy.

Miller is right. Both House and Senate members voting for the budget can be nailed as voting to fund ESCR/cloning by both constituents and opponents.
Apparently leadership began talking about this in April.
For pro-life Democrats to say they didn’t know about this is an unacceptable excuse. They have empowered their leaders, who should not let them vote for something they didn’t know about, particularly if it is concerning an issue that is so extremely close to the heart, like the pro-life issue. It is unconscionable to trick political colleagues who are supposedly on the same team to vote for something they are deeply, ethically opposed to.
