Then how much ultimately would you allow? We already admit over one million legal immigrants per year. That isn’t enough?
And would you even look at reallocating existing visas before calling for an overall increase? Why not abolish Ted Kennedy’s absurd Diversity Lottery visas? That’s 50,000 a year right there. Why not end extended family chain migration? Why not discontinue the settlement of refugee groups who would be better suited elsewhere? Why not be more strict with asylum seekers so we don’t get garbage like the Boston Marathon bombers?
And finally, how can you reconcile support for even higher amounts of legal immigration with supporting conservative principles? Hispanics and (to a lesser extent) Asians are natural liberals. Going left on immigration will not change that. Your policy would hasten the demographic doomsday of conservatism.
