When have we ever seen Kakashi conduct politics? People speak well of him, and that's about it. After the war, who in their right minds will oppose Naruto, and if they do, given the fact Naruto has redeemed and made allies out of the worst kind of sinners in the world, what makes you think he can't manoeuvre through politics? If Hashirama could do it, then there is no reason Naruto can't. Also, I'd like to see anyone lie to him when he can sense their intentions if they're evil. Of course he'd also have advisers to help him learn on the job, much like I imagine Hiruzen and Tsunade (and Kakashi).
Naruto has led more people in the war than Kakashi has considering he was leading the entire army at various points. Also, at the risk of repeating myself from earlier posts, Naruto is evidently a natural leader that people believe in, and he's learned from Itachi that he can't do everything by himself so I doubt he would try.
I don't disagree Naruto needs to hold a rank that reflects his value, but like I said in an early post, more so than Naruto waiting a few year to become Hokage, my issue lies mainly with Kakashi becoming Hokage in the meantime.
