Democrats are setting the policy. Along with RINO's like Hagel and McCain. And then there is the administration.
All on the same side in what they are pressing for.
If you want to argue Democrats will cause damage elsewhere, fine, do that. Mention they'll hike taxes. It's true. But there is nothing the Dems will do on immigration that haven't been done or they are trying to back against the will of the American people right now. It's an empty threat.
Nevermind your position doesn't even make sense. Materials were posted above against the proposition that enabling law breakers is a losing position at the polls. In a Dem town the city council members were tossed out. An incumbent came in second in a primary against a strong border proponent. A popular opponent lost against a Governor that took a stand on illegal immigration. heck, let's not even forget Arnold and Cali! he may be singing differently now, but Grey was tossed over handing out driver's licenses to aliens and Arnold promised to revoke the law. A republican won in Cali on this issue alone. Add it up and we have conservatives and Dems uniting around enforcing the law to the point even incumbents will be thrown out of power.
You have a very reasoned approach in explaining your position. You trust the Democrap/Socialist/Communist more than I do. Under the last Democrap President the USofA bombed the Christians in the Balkins to favor the Muslims. This is the position of the UN Internationalist and the power in the Democrap Party in the USofA. Anything that will further United Nations world government will be supported by the Democraps. IMHO we have here in North America a structure for a government that could defeat the UN! That structure requires commonality with Canada, USofA and Mexico. If you destroy this beginning you will get HELL on Earth, IMHO.
