Tom Tancredo is mistakenly seen as a single issue candidate. That simply is not true. As noted on the Gun Owners of America website Tom has only slacked once on Second Amendment issues, and has effectively recanted that position.

In my mind that was just a reaction to the Columbine High School tragedy. Many of us were pretty torn about that whole thing. Myself, as a professional, I was sickened by the loathsome way that the incident was handled and the very obvious cover up that followed.
I will continue to support Tom, both as a volunteer and monetarily as long as he stays in the fight. I certainly do hope that his debating skills improve though. He missed an awful lot of opportunities during the first debate to make an impact on the next elections.
