I can't comment on whether Congressman Ryan is a janitor, but I can assure that Vice President Biden is not a mop. If your janitor feels a need to mop the floor he'll have to look elsewhere for an appropriate tool.
That's not really a fair fight. Biden has a handicap. I mean, he is Biden.
Vegas has it 7-1 Ryan. Most reputable pundits are predicting a TKO (Technical Knock Out) for Ryan. Personally, l think Biden may go with "No mas!" like Roberto Duran did in the second fight against Sugar Ray Leonard.
I've owned, raised, and trained 50 or so horses during my life, but my husband is afraid of them. Fortunately, he's NOT afraid of the things I fear: mice, venomous snakes, roaches, heights, and tornadoes.
