Under What Conditions Would Pres. Obama Debate Sen. Cruz?

While it makes for a great point, and it probably should be within the realm of possibility, it will never happen:

“Let’s have a debate on Syrian refugees right now. We can do it anywhere you want. I prefer it in the United States and not overseas where you’re making insults. It’s easy to toss a cheap insult when no one can respond, but let’s have a debate.”

[Hat tip: “I want to encourage you, Mr. President, come back and insult me to my face.”]

And I’ll list the reasons this won’t happen:

1. Pres. Obama is a lame duck.
2. Pres. Obama is going to do what he wants regardless of what anyone says.
3. Debating Sen. Cruz would immediately help boost Cruz’s status in the Republican field.

Do you have any other?
