Reader politics quiz

Question: Name a controversy in politics in the last five years where the outrage of Democrats affected real change. My hypothesis: the only Republicans I've seen removed from positions did so only after independent courts or Republicans themselves agreed with Democrats and allowed it to happen (like Trent Lott).

I've been suffering from outrage fatigue for years now and every week it seems like some flaggrant lawbreaking on the part of the President or his party is going to have consequences, but it never does. Nothing ever seems to come out of anything except some quips on the Daily Show.

Dear readers, I ask you for some success stories. What change have the Democrats actually acheived on their own in the past five years?
