None describes him exactly: He so often behaves like a gump that it hard to imagine how he became president. He's not quite a chump - because I don't know of any incident in which someone else has succeeded in deceiving him. I see him being a grump now and then - though more often its petulance. He does tend to dump on anyone who displeases him and won't hesitate to dump them from their jobs. He loves to dump on the media, liberals, non-whites, or women who have accused him of inappropriate behaviour or rape. He's more than a little plump. He has a flat and saggy rump. Even if one loathes the sharp suit, white shirt and tie, one could not call him a frump. I've never seen him slump, though I'm sure he must when he gets home at the end of the day. He certainly hasn't succeeded as a pump to the American economy - the country more in debt than ever and there's been no improvement in wages or more jobs for those who need them. He's definitely a difficult hump, stump or hurdle for the Dems. I do see him as something of a bump in American politics and history - a rather large one that will that some time to recover from after he's gone.
