Except that you know the issue being discussed to which Rush is responding was not the amnesty issue, so good deflection for a person who refuses to argue an issue.
I interpret it as Rush saying that he defended people “who publicly articulate” “the ideas I have,” in this instance, the idea is that Obama is acting intentionally, and the person who articulated it was Rubio.
Then Rush goes on to say, “Even if they might have a credibility problem here or there.”
Given that Rush was defending Rubio, the biggest credibility problem Rubio has is Gang of 8.
And the phrase “problem here or there’ minimizes it.
