Interesting to watch, as morphs sometimes are, and to read to see how many of the quotes are familiar. Many are not.
For instance, the quote for William Henry Harrison, famed one-month president: "All the measures of the government are directed to the purpose of making the rich richer and the poor poorer." Which, however true it is, seems like an odd thing for a politician to admit.
A bit of investigation uncovers a longer (non-tweet) version of the line, which is, "I believe and I say it is true Democratic feeling, that all the measures of the government are directed to the purpose of making the rich richer and the poor poorer." It is from a speech Harrison made as president-elect in late 1840, having just defeated the Democratic incumbent, Martin Van Buren. It seems like Harrison was offering up some Whig criticism of the rival party, rather than ruminations on plutocracy.
Still, a fine list of pithy quotes. Watch especially for Nixon's.
