Well, yes it did seem cynical, but that seems to be a reasonable response to what has gone before.
The poster did not say enforcement was impossible - only that it has not been practiced in the past and there is no current reason to believe things will improve in future.
Since most here realize that there are adequate laws on the books today (including funding for twice the fence this bill offers):
A more appropriate question ('what do you propose?') would be 'what can we do to see that existing immigration laws ARE taken seriously by our own government?'.
Since most here would have to agree that the sainted RR wasn't perfect in all things:
A second question might be 'what can be done to stop another amnesty screw up by another Republican president only 20 years after the last one?'
And, of course, the fatal third question is 'how do we do that without handing 2008 over to the other face of Bill?'
When you have something that is not working I think you figure out if you fix it or throw it out. As I am not intrested in waring a burqua, I do not favor surrender to al Queda or the invaders.
