1. Independent
2. Centrist Conservative
3. Republican/Democratic/Libertarian
Would these be the tickets?:
Republican: Marco Rubio/Kelly Ayotte
Democratic: Martin Heinrich/Kirsten Gillibrand
Libertarian: Ron Wyden/Rand Paul
Centrist Conservative: Brian Sandoval/John Kasich
Rubio/Ayotte would be Republican. Heinrich/Gillibrand would be Democratic. Wyden/Paul is an odd ticket, definitely not Libertarian; Wyden would be Democratic, and Paul would be a libertarian-leaning Tea Party candidate. Sandoval/Kasich is definitely Centrist Conservative.
Wyden and Paul are left-libertarian and right-libertarian, respectively. I was seeing the extent of the libertarian coalition.
