Hillary Clinton - John F Kennedy (She has an ambitious agenda, but the current state of government isn't conducive to getting big legislation through, and thus her administration is known for its behind-the-scenes decisions and strategic changes in US foreign policy, rather than sweeping legislation)
Bernie Sanders - Barack Obama (That whole hopey-changey thing, and again probably not great at getting significant legislation through congress)
Lincoln Chafee - John Tyler (Why is this guy president again? Makes decisions completely out-of-step with his party's elite)
Joe Biden - Bill Clinton (Likable, and probably gets high approval ratings, but often fails to see the broader picture, and much of the actual legislation that comes through ends up getting re-written or repealed a few decades later)
Donald Trump - George W. Bush (Completely ruins US foreign relations for years, might actually get legislation through, but much of it is dramatically flawed and replaced during the next administration)
Jeb Bush - Gerald Ford (Pretty blah, but doesn't do all that much damage. Stuck with burdensome legacy)
Ted Cruz - John Adams (Inspiring lawyer who completely ignores the Constitution while in office to further his agenda and sideline his opponents)
Chris Christie - Richard Nixon (Probably wouldn't be all that bad policy-wise, but is generally surrounded by a veil of corruption and appoints a terrible cabinet)
Rand Paul - Ronald Reagan (Adored by his base but reviled by his enemies, he significantly changes the direction of the Republican party)
Hillary Clinton = JFK?
?
The word for you is Sycophant
Chris Christie - Richard Nixon (Probably wouldn't be all that bad policy-wise, but is generally surrounded by a veil of corruption and appoints a terrible cabinet) That would be Hillary
