Congressman Bart Stupak initially refused to vote in favor of the healthcare bill, but agreed to do so because President Obama said he would sign an executive order to not allow federal funds for abortions. Just as he said he would, Obama signed the executive order. Whether this executive order means anything in the long run is unclear, but neither the pro-choice camp nor the pro-life camp think it does.
So if the executive order is essentially meaningless, was Stupak stupid to give his vote for it? It would appear so, as he's not getting the love he seemed destined to get.
