Not very well I must admit. But it only fair to point out that the Supreme Court Justices who voted to grant citizenship rights to corporations (whose interest are, more often than not, quite apart from those of real citizens) were appointed by Republican presidents.
True, if you're including Grant, Hayes, Arthur, etc. as Republicans (which they were, although the Republican party of the 1880s is a bit different than that of today). Also, you'd need to include Democratic-Republican Presidents like Madison and Monroe on that list.
Corporate personhood is NOT a new phenomenon - it's been a well-established principle since (for varying purposes) the 1880s or the 1810s.
