The vast number of people in America are libertarian conservatives--limit goverment, limited government power, limited spending, reduced government regulation, lower taxes, government out of our lives. Run on that platform and then do it, and people will vote for you. Run on that platform and then do the opposite, and people will abandon the GOP.
But that is not borne out by this poll! I won't say this poll is accurate or not, but you cannot argue that the reason for these results is that conservative principles aren't being followed because the reason for the poll results is exactly the opposite of that. Secular principles, more government, etc. are what this particular poll suggests the people want.
