Politics is like Mario Kart, and here's why...
Anyone who used to play Mario Kart 64 for Nintendo should be aware that during each race, whenever you use one of the power-ups against your opponents such as the mushrooms and turtle shells, the A.I. cheats and speeds up so that you can never build such a comfortable lead regardless of which character you use. Also if you fall behind in a race, you are unable to speed up like how the A.I. does, and it's extremely tough to catch up.
This is how I see it between Democrats and Republicans. Whenever a Republican slips up and makes some type of offensive remark or gaffe, they may get in a bit of hot water temporarily. But eventually, things cool down, and then they and the media usually go about as if nothing happened (like how Rush Limbaugh still has yet to be fired for his misogynist comments). However, with Democrats, if one of our people says or does something foolish, usually they get pressured to resign, they get fired, they go down in polls, and the media is all over it.
