The Senate just voted down the bill to strip funding of Planned Parenthood by a 58 to 42 margin, with five Republicans joining all the Democrats to oppose defunding.
The lack of support for defunding Planned Parenthood in the Senate demonstrates why it would have been so hard to get it inserted into any final budget deal, even if House Speaker John Boehner, R-Oh., was willing to shut down the government over it.
If it were just a matter of a few votes, maybe. But in this instance you're talking about a gap of 18 votes given the 60 that would be needed to defeat a filibuster.
The five Republicans who voted 'no': Sens. Olympia Snow and Susan Collins of Maine, Scott Brown of Massachusetts, Mark Kirk of Illinois, and Lisa Murkowski of Alaska.
