Rubio, but Trump and Paul's wives are also hot.
For what it's worth, my wife thinks Rubio and Paul are the best looking candidates.
Interesting. I think Paul's wife is the best looking. I agree Rubio's wife is good looking, but not as hot as Paul's. I think Trump's wife is over rated, his daughter is somewhat good looking but his wife doesn't appeal to me at all.
I would think most women would say Rubio, though I'm sure some would answer Ted Cruz.
My own opinion
1. Ivanka by far, even though she's not part of this contest
2. Melania. She has an ethnic look that might not appeal to some.
3. Paul's wife. She has a classic cookie cutter Southern wife look to her. Pleasant to look at.
4. Rubio's wife. Good looking but aged
5. Kasich's wife is pretty.
5. Cruz's wife
