What Will We Hear Tonight?

In the last Republican debate, we heard primarily four things discussed:

1. Iran
2. Planned Parenthood
3. Immigration
4. ISIS

Four topics I didn't hear mentioned:

1. Global warming
2. Economy
3. Deficit
4. Government corruption & scandals

Interesting. You'd think Planned Parenthood was the modern day Al-Qaeda. Please. 

Meanwhile climate change / global warming is an enormous threat, the economy has been doing fine post-GW/Cheney, the federal deficit has been shrinking to zero, and Obama's two terms thus far have been corruption/scandal-free, something that certainly does not get enough media attention.

Yes, what will be the sky-is-falling topics tonight, I wonder.
