American politics in the 21st century

We are currently in Stage 3.

1. Republicans take power and wreck the country.

2. Tired of the wrecking, the people vote the Democrats into power.

3. Democratic stupidity and Republican obstructionism prevent the Democrats from un-wrecking the country.

4. Tired of the wrecking, the people vote the Republicans into power.

5. Repeat 1 through 4.
