Liberals will vote for whatever candidate isn't conservative, like dear old mom and dad. They don't care if he/she is a communist, road killed skunk, or an oak tree, they'll vote for 'em.
Conservatives are fussy little beitches. Nobody but Mr. Perfect for us.
So, we get another liberal.
Do you suppose the republican field having 16 candidates starting out may have been by design? Think how many conservative voters you can discourage into staying home with 16 candidates to drop out one by one!
