Can't see the bank account without some sort of legal action. Not sure what you're imagining but that seems like a silly line of thought. Do you really think every financial move a person makes goes through their bank account? If anyone is stupid enough to put payoffs or other ill gotten gains in a bank account along with their "normal" money then they're amazingly stupid. I would find it VERY hard to believe that anyone would do that.
It may be odd, but I don't find it relevant. He can hide money under his mattress if he wants, I really don't care.
This is a distraction from any real issues. If people want to "take him on" then do so on the issues he will deal with as a member of the house.
I find this whole "let's gettem" approach to politics a BIG distraction from real debate on real issues. Not to say that we should allow politicians to do whatever they want but let the investigators do that. So the media spend their time with BS like this instead of asking the real questions on real issues. The public debate is not engaged for the sake of a non-existent bank account.
