You must add three more words: Stop illegal immigration! I don't believe that the anti-illegals are a small minority either. Hewitt is wrong about this issue.
The people whose sole issue in life is immigration are a small minority and always will be. They're no different than the people who vote (or don't vote) based solely on abortion, race, gender, etc. Of course single issue types are also very loud and tend to get lots of attention despite their small numbers.
