The thing is, immigration is growing not remaining static, immigration in the last decade was HUGE compared to previous decades and still growing. We are in what is joking refered to as the "War on Terror", I prefer to call it the "War of Terror" and it isn't being waged against Islamic extremists, but on native born Euro Americans.
How else does one explain the sudden blindness of poll watching politicians when it happens to be an immigration opinion poll?
I get RNC fund raising mail almost every week. Many include surveys on major issues. What I noticed in the most recent letter was that the enclosed survey had NO questions about immigration. I suspect they didn't like the results of previous surveys on the immigration question and are now in full denial mode.
