once people with conservative beliefs start saying Trump doesn't represent them.
Yes he does.
They did the same with Bush.
GOP presidents fail because their beliefs encourage them to support policies which fail.
Things like lowering taxes to promote growth (only works when taxes are extremely high), or climate change isn't happening (a really wonderful logic - wait to prove it is so by turning earth into the planet Mercury because science demands post hoc proof).
It's the ideas, stupid.
