I just took a look at the words I chose subjectively and applied them to the transcripts of each of the "debates"; really question and answer sessions that turned into mico- speaches by the candidates.
But the candidates' responses where choreographed and the words were chosen. As the infamous Idi Amin Dada once said; "Sometimes people mistake the way I talk for what I am thinking." These politicians are masters of deception, each with ulterior motive.
Don't get played -- what they say is what is what they say --- and the winner I pick is <drum roll>

There are other nuances to be gleaned for these keywords that they use as their buzz words or voter hot button words that are indicative of candidate/party philosophy and intent. The Republican debate was more limited to foreign policy while the Democrat debate was more general issues.
The word ''Muslim' was R=32 D=11
The word 'refuge' was R=23 D=10
The word 'bomb' was R=8 D=0
