Spin what?
You aren’t making any sense, Scott Walker has attended a gay marriage event, what is there to spin or not spin about that?
I see that Ted Cruz agrees with Scott Walker that marriage is a state issue.
You can drop the other nit-pic you have because it’s obvious that Cruz would not agree with your position about Walker attending a family gathering (it wasn’t a wedding).
In light of the fact, that Cruz has no problem holding a fundraiser in the home of prominent gay couple, this is a dead end argument for you.
