Do you feel that when "regular" people are Republicans, it's because they just don't get it?

I am wondering how “regular” people (i.e. the middle class and lower class) are Republicans, it’s because they just don’t get it. The Republicans talk about tax reform, yet they don’t specify how they want to reform the tax code, exactly. They talk about being regular people (Mitt’s wife, Ann Romney, kept referring to Mitt as a regular guy), yet he’s a zillionaire and the Republicans protect themselves with their tax cuts to the rich. At the RNC, many speeches were full of lies and inaccuracies. How could a regular person, i.e. not a rich person, fall for this and think that voting for a Republican president would benefit them?
