Even if they were set up...Sanford chose the wrong path. There is no one else to blame for this folly but the man himself.
I think it speaks more to the point that there is some inherently wrong with people in politics. The system seems to attract people with some pretty serious character flaws.
If you look at "the system" that we've let the politico's create for themselves (and the system WE pay for) it's really no wonder that it tends to draw corrupt figures. By and large it has been my observation that the majority of people who are drawn to politics are people who couldn't make it in the private sector. We see this over and over. I mean, really, what else would folks like Barney Fwank or Obamalamadingdong do were it not for politics? Consider the perks of free health care for life for themselves and their family members, cushy retirement bennies, contacts with prominent members of the business community who would otherwise never give these political creeps the time of day. Most of the business community who deal directly with political figures are perfectly willing to go along with whatever the politico's do so long as they get their take or have some measurable influence. It's a disgusting mess.
Politicians and diapers should both be changed often and for the exact same reason. This is precisely why we voters, the ones who are supposed to be in charge, need to make 2010 the year we flush the incumbents.....whether or not the voters have had enough remains to be seen, but I won't hold my breath.....
