IMHO, that day will happen....and it will more likely than not occur because of the pourous borders. It's only a matter of time. The politicians will then cover it up....will never admit they came through Mexico (and Canada). To think otherwise one must have their heads in the sand (or another place), as the politicans currently do.
We will do something...what, I don't know. I suspect we will drive them from office. We'll be putting up pictures like sKerry and hillary hugging and kissing on terrorist. They will all draw our ire.
Our open borders are a sick sight.
