Someone once made the observation that rodeo bulls must be easily distracted. A rider tries to ride out the time on the back of one of those bad boys. The bull is mad as hell, and once the rider is off, the bull is ready to rip the guy apart, then trample the guy into the ground.
Hey wait. Where did that rodeo clown come from? In an instant the bull forgets about the rider and goes after that clown.
Donald Trump is that bull. Strong and focused, until he gets distracted by that clown in the colorful suit. The Clinton campaign has figured it out and applied it to their advantage. Remember that first debate between Trump and Clinton? All it took was a reference to alleged remarks he made about Alicia Machedo. And there went Trump like a bull after a rodeo clown. The rider calmly walked away and watched from behind the fence.
There are probably more clowns hidden away, waiting for the bull to throw the rider.
P.S. Maybe all those strange clown sightings we hear about are actually Clinton supporters simply rubbing our noses in bull manure.
