Two decades into the national discussion about homosexuality and the military, Sen. Collins has decided to back allowing gays to serve openly.
Kudos to the junior senator for the about-face. And for breaking with her allies on the far right. I'm sure her old friend Rick Santorum won't be too thrilled.
But let's not pretend this makes Collins some sort of trailblazer for justice. It doesn't.
There was a time when this sort of stand would have really helped shake things up. But that time is long gone.
