You can't blame the wife, even Hillary, for the behavior of a serial cheater. Bill was credibly accused of raping a woman in UK when he was there at Oxford University, before he married Hillary. A cheater is a cheater. They may even unconsciously pick a woman to marry who gives them the appearance if an excuse.
When I visited the Clinton Double Wide Presidential Library in Little Rock, the guide even joked about how Bill brings co-eds from nearby Univ of Arkansas School of Government up to the 4th floor love nest.
