When it comes to MANY issues, Marco Rubio will probably be trying to stake out positions between Cruz and Clinton.
He has already revised his amnesty/illegal immigration position several times.
You’re either a conservative or a liberal. The minute you stray on only one thing, as small as it is, you are no longer a conservative. Moderate isn’t an ideology. It’s a spot on a fence post which knocks you over depending on how the wind is blowing.
Makes for good politics, but horrible ideologically.
