you are making to assumptions i would not make.
1 there will be a party change in 2016
2 if there is a party change, the new party will care.
Hope you are right on #1. As long as a true conservative is elected.
Think you are wrong on #2.
Just like Bush did nothing to go after Clinton’s lawlessness, any Repub that might be pres will simply want to “move on” after all the criminality of the O admin, Hillary, etc. and all will be forgiven and forgotten. It’s a general rule of presidencies that when you win office, you don’t go after your predecessor or any of his buddies.
