Did Barack Obama vote to withhold treatment to infants surviving abortion?

This question continues to dog the Obama campaign and now the National Right to Life organization has amassed documentation regarding the claim and the Obama response.
Rather than reproduce it all here, I am going to post the link and comment more a bit later.

The Weekly Standard has some reporting on this issue as well.
Jill Stanek, the Illinois nurse who blew the whistle on infants left to die has ongoing coverage of this controversy.
The New York Sun has an article clarifying the issue even more. It seems Obama is now saying that the Illinois bill might have impacted Illinois law but that he would have voted for the federal version since there was no federal abortion law.

Indeed, Mr. Obama appeared to misstate his position in the CBN interview on Saturday when he said the federal version he supported “was not the bill that was presented at the state level.”
His campaign yesterday acknowledged that he had voted against an identical bill in the state Senate, and a spokesman, Hari Sevugan, said the senator and other lawmakers had concerns that even as worded, the legislation could have undermined existing Illinois abortion law. Those concerns did not exist for the federal bill, because there is no federal abortion law.

However, he is a prime supporter of the Freedom of Choice Act which would become federal law. Does that mean he would support the repeal of the federal Born Alive Act?
