Rode him like a one-hump camel (?)

What does this mean, I wonder?

RODE HIM LIKE A ONE-HUMP CAMEL -- ".(State Auditor George) Adkins made a reputation pursuing state spending in former Gov. Julian Carroll's administration. 'We rode poor old Gov. Carroll like a one-humped camel,' (Michael Wayne) Gayhart said, chuckling. 'I don't mean that in a bad way, but we looked at every dirty little thing.'." Gayhart is a candidate for auditor in this year's election. From an article, "The Race for auditor: Both parties' hopefuls discount front-runner," The Herald-Leader, Lexington, Ky., May 14, 2003.

(Correcting newspaper.)

What an odd expression. It clearly means "we hounded Gov. Carroll" or more colloquially "we were all over Gov. Carroll's ass", but I'd have thought that riding a one-humped camel was a difficult thing to do.

I can't figure it out. Maybe the auditors held on even though the ride was rough? Or there was no place to sit on a one-hump camel?
