The game here, is to throw Marco Rubio, or any potential contender, off message, early and often. Irrelevant questions (age of the earth, which is subject to a great deal of diverse opinion), and moving the dialogue from things that OUGHT to be considered. Senator Rubio was talking past the question, directing his response to his supporters and partisans, and attempting to steer the discussion back to the subjects at hand.
It may be necessary to contact the voters directly, WITHOUT the filter passing through the media.
The framework is being set up to picture Senator Rubio as a theocrat. And therefore, indistinguishable from, say, the Pope, or maybe Billy Graham. But definitely anti-science.
How about, “Who gives a crap about how old the Earth is, what does it have to do with anything? Let’s talk about the future, not the past.”
