Will Tax Issue Mortally wound Romeny?

[opebo]

To say that the voters don't understand a tax return or care about Romney's isn't precisely the same thing as to say this issue will fail to wound him at all.  Keep in mind that the vast majority of voters are voting in a simple emotional way - yes, they are indoctrinated in such a way by the capitalist system that they cannot think critically or understand simple things like a tax return, but they will see Romney bumbling along, looking weak, dodgy, and less-than-masculine about this, and probably several other issues.  

It is this that hurts him - the attacking and the failure to respond effectively.  For most voters, this  back-and-forth makes sense only in the same way two groups of dogs barking at each other makes sense - there is no 'content' for them other than who is loudest and most confident, and who dominates the other with facial gestures, body language, and tone of voice.

So, I would say this could have a very mild negative effect in this fashion, but nothing remotely mortal.
