You claim that 100% of all conservatives are for "secure borders" . I am pretty sure that this figure did not emerge from any serious poll that you took.
All I hear from the immigrant-hating right is how they refuse to do anything until the "border is secure". But they never, ever, provide any figures regarding what they would consider a secure border. Unless it is absolutely demonstrably 100% secure, then, they will continue to repeat this mantra, never giving what they consider to be acceptable figures.
And establishing a plan to allow someone who a job that he does well has lived here for a dozen years and has several children born here is unrelated to other people ostensibly sneaking into the country. All we hear from the ratbag right is "no amnesty!, no amnesty!" to any and all proposals, even those that deal with people whose children were born here and have been model citizens. Of course, the ratbag right knows that most of these people will not vote for Republicans who think of them and their kind as undesirables. I suppose a hideous bigot like Tom Tancredo might get 2% of the Mexican American vote, but the other 98% want affordable health care, better education for their children, job training for the unemployed and other things that the ratbag right thinks of as "Socialist".
Mexico has three major political parties: two of them have some form of the word "Revolucion" in their names, and the third, Acción Nacional, is affiliated with the Catholic Church, which these days is no best buddy of neocolonialism, either.
