This one should be easy.
The Republican Party is in serious political trouble today because:
1. The Democrats have suddenly become very good at selling socialized medicine to the voters.
2. The Republicans pursued traditional conservative policies -- reducing the size of government, balancing the budget, and protecting the value of the dollar -- and the voters did not like the results of these austere measures.
3. The Republicans kept their promise to avoid unnecessary nation-building, but the voters prefer a more interventionist foreign policy.
4. None of the above.
