Gutless would imply that he agreed with your position and simply lacked the courage to act on it. The truth is that he doesn't agree with your position.
I disagree. In fact I will go so far as to say that most Republicans AND DEMOCRATS know that the massive illegal immigration problem is a disaster for this country but in a disgusting display of unanimity refuse to do anything to alienate Hispanic voters. It all comes down to gaining,holding and manipulating power.
The good of the nation be damned.
