How do you turn a noble undocumented worker into a sinister, conniving illegal immigrant?You do it by hiring him to cut the lawn at Gov. Mitt Romney’s house, or at least that’s how the bow-tied bumkissers at The Boston Globe pulled it off.The phrase that is usually frowned upon by the Globe - illegal immigrants - was used 11 times in a front-page story Friday. Yesterday, those same dreaded “illegal immigrants” made it into the lead sentence of the follow-up story....It’s all very confusing, but I think I have a rule of thumb.If you get paid by a liberal Democrat, you’re an "undocumented worker."If you get paid by a Republican, you’re an "illegal alien." Comprende, amigo?
