It may be legal, but is it moral? ethical? patriotic? to pay NO federal income taxes?  A candidate that criticizes big corporations for moving offshore to avoid paying their "fair share" seems hypocritical when doing the same here.  The point can be made that the rich give megabucks to worthy causes, pay local and state taxes, etc., but "something" tells me that if tax returns were made public, the records would show little evidence to indicate that "someone" was even meeting that threshold.
