Rick Santorum is not sexist, but he does have some concerns

The Pentagon: Women can serve in more, though still not all, critical combat roles than before.

Rick Santorum:

I do have concerns about women in front line combat. I think that could
be a very compromising situation where - where people naturally, you
know, may do things that may not be in the interests of the mission
because of other types of emotions that are involved.
