You CANNOT..in 2012...run ANY political campaign that is ambiguous about your immigration position in the current job market.
Unemployed Americans are looking for assurances of their governments concern about THEIR plight...not that of businesses forced into looking for disposable labor because of onerous tax and regulatory policy.
Illegal Labor is the Feds out for preserving the status quo regarding Taxes and Regulation...and is the ultimate litmus test as to the candidates in question commitment to meaningful regulatory and tax reform. If they are wishy-washy on the subject...they have no real intent to disturb the DC status quo...no matter how big their cowboy hat and six-gun.
