A new media study among 1,378 Americans revealed that among political parties, more Republicans (73%) reported spanking their children compared to Democrats (60%) and Independents (61%).

 

In addition, a slightly higher number of Republicans (89%) reported being spanked as a child compared to Democrats (87%) and Independents (86%). Despite recent study findings, the vast majority of Republicans (78%) did not think that spanking may cause aggression in children, while fewer Democrats (58%) disagreed with the findings.

 

So now you know, all you yellow-bellied surrender monkeys -- you just weren't spanked enough!

Fairly small differences... but it does fit the stereotypes.

I thought they discovered the link between cognitive dissonance and corporal punishment a long time ago, but supplementary evidence is always welcome.
