I've noticed a trend.
Step 1: Democrats do something unprecedented.
Step 2: Republicans, who have never contemplated that action before, not only do it, but take it to new heights.
Step 3: Democrats complain that Republicans are abusing the process.
Examples: Filibustering court nominees for political purposes, using filibusters to prevent major laws.
My prediction is that Democrats breaking this precedent will come back to bite them.
