There is only ONE rational explanation if one bothers to look at the leading news of that week, and that was the Minutemen. It was clear who the reporter was referring to with the question and who Bush was referring to with his response in the context of the news. In addition, McClellan refused to clarify or elaborate on Bush's statements. And given that Bush is still spewing some of the typical pro-illegal talking points (doing the work Americans won't do, bring them out of the shadows, yadda, yadda, yadda), his position is consistent with those who view the Minutemen as lawless vigilantes.
So you and a few other folks can try your denial game all you want. But you're only fooling yourselves.
I "spew" some of the typical pro-illegal talking points but do not view the Minutemen as lawless vigilantes - as long as they obey the law, I just think they are misguided - did you know that the reporter asked the question in SPANISH?
