Fun fact: if Rand Paul wins the 2016 Republican presidential nomination and chooses Paul Ryan as his running mate, the ticket would be "Paul-Ryan 2016." Of course, Rand Paul's advisers might pale at the prospect and, breaking with the typical conventions of campaign literature, refer to the candidates by their first names: then the ticket will be called "Rand-Paul 2016". Much better.
Sadly, it doesn't work the other way. A Paul Ryan-Rand Paul ticket just ends up as Ryan-Paul 2016, which isn't nearly as fun.
