Let me see if I understand this...
If you have a strongly held conviction that happens to be at variance with, say, 55% of the electorate, you should stifle that conviction in order not to risk the chance of losing an election?
And these guys wonder why they keep losing?
The electorate doesn't want candidates who will tailor their message to what 55% of them say they want.
They want someone who will convince them that what the candidate believes is what they should believe.
Republicans use polls to figure out how to sell their ideas to the public.
Democrats use polls to figure out what ideas to sell to the public.
Guess who is winning?
