Interesting tickets - personally I think Kasich will choose someone to the right of him to shore up the conservative vote, but still a solid ticket. After barely winning the nomination, Democrats will be dismayed that Hillary didn't select a "true progressive" as her running mate. Kasich/Sandoval hammer down on their accomplishments, arguing that they can replicate the successes in their state to the entire nation. Clinton is easily overshadowed by her running mate, who, while having charisma and a pretty face, is unable to fully convince the American people that he's qualified enough to potentially become President.
The campaign stays pretty close until the final weeks, when undecided voters slowly start to break for Kasich, who is seen more favorably by moderate voters.
