I'm sorry but are you completely out of your mind ?
Can't you really see how much of a problem it is for someone seeking supreme office to be declaring his income in other countries, especially in a fiscal paradise like neighboring Switzerland, when he will ask his citizens to increase their fiscal effort because of "the crisis", whichever this may be ?
Can't you really see how outrageous it would be ? Would you have Romney living in Luxembourg six months a year and financing Luxembourg universities more than US ones while being US President ?
Actually, I feel am I being far more rational here. It may be an electoral liability, but it's not a liability towards ones ability to hold the office. I am being quite rational here. I want the candidate who is best for the nation and by extension best for me to win. Regardless of my personal feelings about them. If I had the option to benefit everyone, including me, on the condition that someone I didn't like benefited the most, I'd still opt for that option. In fact, if everyone thought rationally thought like this, wouldn't we all be much better off? We'd certainly put an end to stupid things like war and protectionism.
