Not the issue.
The issue is Perry attending an organization which is 100 percent pro-amnesty and pro-open borders and pro illegal alien, while giving speeches and bumping bellies with them, does nothing but lend credibility and credence this racist organization.
I admit that attending that function was a boneheaded move on his part -- but even more so, because he reaped no political benefit from doing so (which is the point I've been trying to make, albeit unsuccessfully thus far).
