With elections in 2006 coming, and the GOP behind in the polls over budget, border, and ports; sweeping all this bad PR aside with a trial of two Dem Senators for "treason", I think the GOP will not play along with protecting fellow Congressmen. Watch the indictments will come in the spring and leaks/investigations throughout the summer (slow news period). By September, the Dems will be badly bruised.
I hope you are right but I am less than optimistic.
