I’m not sure anyone believes that Trump is a Conservative. His personal message is more Nationalism than anything else and this is what has captured the attention of the non-political type.
These people are now scared by everything that is wrong in this country. They want someone who promises to stop the illegal invasion, not import terrorists, bring back jobs, improve the economy and kill terrorists in there own homes. None of these positions are exclusively conservative, and given Trumps known record for achievement, they believe he can deliver.
Make no mistake, even though a slim majority of citizens self identify as conservative leaning, there is no national outcry for more conservatism. Traditional conservative institutions such as churches and the military continue to lurch leftward and the war on traditional values and the nuclear family continues unabated.
Conservatives have allowed their opposition to define them in the public consciousness and now hardcore conservatism actually terrifies too many people, conservatives included.
There is a lot of work that needs to be done to actually move the country back to Constitutional conservatism.
Any time the actual principles outlined in our Founding documents are in play we have true conservatism. Because those documents are based on long-held Judeo-Christian ethics and philosophy. When we veer from those we enter areas which are not conducive to truth.
