This is not expected, but neither is it a surprise.

Aside from everything else: honestly, Rep. Schock was showing signs of Invulnerability Syndrome. Legislators get that after their third or fourth term, sometimes: they think that they’ve got this, so they can do whatever they like. It doesn’t… really work that way, as many a politician has subsequently discovered. As Aaron Schock has just demonstrated.
PS: Take the special election for IL-18 seriously. The voters have been known to spank the party, if they can’t spank the politician. It happens quite often, in fact.
