Charlie Wilson is not giving Hillary Clinton high marks ... for dancing.

We got Charlie at LAX Friday, arriving after headlining a Hillary for Prez rally in South Carolina where he got the candidate to bust a move ... sorta.

Charlie gives her a 6 ... which is generous, but he says there's a plan for improvement..
