I'd vote Merkel/Kim (Jong Un) against Hillary if the GOP nominated them but this ticket would make me pine for Romney/Ryan. Icky.
A Trump/Kasich ticket would definitely be to the left of the Romney/Ryan ticket, not that the Trump worshipers on here will ever admit that.
Although... they DO “balance the ticket” better, personality wise (Trump-outspoken loose cannon, Kasich-bland colorless hack)
