According to this post at Riverdaughter hitting us over the head with Roe vs Wade was the plan all along – at least Chuck Todd knows so:

The SCOTUS, Roe v. Wade and women’s issues was the BO campaigns “ace in the hole” according to Chuck Todd from MSNBO network. The BO spokesperson told Todd that they would use any means necessary to beat Hillary and if women were offended, they would come back to the party during the GE because their plan was to “play the Roe v. Wade card.” THAT is a direct quote from the BO campaign via Todd.

So, it’s not that they didn’t notice any sexism, they planned how to cover for using it afterwards.

I don’t think he meant for us to see this video either where he tells fundies he opposed abortions (min. 1:50 mark)
