I agree with NCC that this is following Fox shtick.
Not that Fox has done exactly the same thing towards children, but the general shtick of poking fun at the other side when something appears to be amiss with their accepted image with the public. Like when Obama prays in church or some ultra-liberal congressperson salutes the flag.
I'm not sure this is "Fox Shtick" or "MSNBC Shtick". This is "moron shtick" IMO and both channels have plenty of morons.
That's true, but in the cable news business Fox is the ratings leader so they set the tone. These networks are driven by ratings and money, and are constantly walking a line they sometimes cross.
I'd go as far to say it's a psychological reaction to what they created. The media likes to narrowly define guys like Romney and Obama because their audience loves to be lazy and think of them that way. That equals ratings. When their narrative goes astray all they can do is make fun of it.
The left-wing media perspective is - oh look, Romney has an adopted black kid. It's so different than the exaggerated out of touch rich white guy image we created. I believe there is some truth to that, and it was enough for me not to want him as POTUS, but to think he's a guy who would never adopt a black child is ridiculous. The right-wing media does the same thing with Obama. It's pathetic.
Both of these men are far more complex than their political image. Isn't it funny how we always discover later that former presidents are not exactly the person we thought they were in office?
