"Trophy Candidate"

A reader writes:

Not knowing anything about the Republican field, I heard about the pick this morning and looked up the stories on her. 

My first thought was:  Trophy Candidate.

The visuals were strange. She looked like the promising student that an older professor admires (and has a bit of a crush on). When she called McCain her "partner," it sounded odder still. He comes off as her guardian or foster parent.
