Would it make a difference to you if it turned out some of his tax shelters were actually not legal? Or, do you think anything goes?
I think there's more important things to worry about regardless.
If some of the tax shelters were illegal, I wouldn't look at it as a positive, that's for sure. I would still find it a minor issue compared to the current state of the Union, its economic sluggishness of nearly half a decade, and the jobless rates that show no signs of improvement in the near future.
Above everything else, I think the fact that a presidential election seems to be based around the proponents of both sides arguing on BEHALF of their side by saying "the other guy is actually WORSE than our guy, can you believe that!?!" says more about how piss-poor things are than anything.
I've said before that people tend to choose their political party more because of their dislike of the OTHER party than any real belief in the worth of their own party. People are always more fired up to vote AGAINST someone than they are to vote FOR someone. Right now there are a lot of people more than ready to vote AGAINST Obama...and the Obama campaign is working its ass off to find ways to get people fired up to vote against Romney, but
potentially unflattering tax returns from years ago isn't going to have any legitimate impact on people who've lost their jobs, had their home values disintegrate, and find themselves being vilified by the current administration for not wanting to give up even more.
If the economy was revving forward, everyone had jobs, and the economic outlook was shining bright....then Romney's tax returns would be much higher on my list of "things to base my presidential vote on," but that's not the case.
