Planned Parenthood hired a Democratic polling firm to find out if taxpayer funding of Planned Parenthood is still popular, and found out that 64 percent of voters still want federal funding for the organization. Here's the question that voters were asked:
Some Republicans in Congress say that because of the undercover videos released by the Center for Medical Progress, there should be an immediate vote to end all government funding for Planned Parenthood, including for services Planned Parenthood provides, such as cancer screenings and family planning. Do you strongly agree, somewhat agree, somewhat disagree, or strongly disagree with the Republicans who say Congress should vote immediately vote to end all government funding for Planned Parenthood, including for services Planned Parenthood provides, such as cancer screenings and family planning?
As you can see, the poll doesn't say anything about the fact that Planned Parenthood harvests and sells the organs of aborted babies or even that Planned Parenthood performs any abortions at all. It merely states that Planned Parenthood provides "services" such as "cancer screenings and family planning," services which will remain federally funded at other clinics (not that the poll tells you that either).
I'm honestly not sure what the results of an unbiased poll on defunding Planned Parenthood would look like. Most voters probably haven't heard about the latest undercover investigation, and I suspect that a large number of voters don't even know that Planned Parenthood performs more than 300,000 abortions per year.*
What we do know is that defunding Planned Parenthood has not proven to be politically toxic even in Democratic states. In 2011, Scott Walker defunded Planned Parenthood in Democratic-leaning Wisconsin and Chris Christie Defunded Planned Parenthood in heavily Democratic New Jersey.
Christie defeated his Democratic challenger Barbara Buono by 22 points in 2013. Walker won a recall election in 2012 by 7 points, even though the electorate that showed up to the polls backed Obama by a 7-point margin. In 2014, Walker won a second term by defeating Democrat Mary Burke by 6 points.
A third video about Planned Parenthood's involvement in human organ trafficking was released earlier today. You can read a summary of the video and watch it here.
*Update: Ramesh Ponnuru points to a 2013 poll that found a "full 88 percent of respondents said they were familiar with Planned Parenthood, but only 45 percent said that they thought its affiliates perform abortions."
