What they say and what they do don’t match.
Trump needs to put his mouth where his money is (or has been).
He’s invested millions of dollars supporting a very liberal agenda up until recently. His coincidental conversion to the republican party seems a great ploy at either subterfuge or hedging, both Characteristically Trump strategies.
His record does not support gun rights for the general public. They can say whatever they want up until they are elected. To know what he really thinks (and will likely do in the future), look at his past.
Same goes for most politicians.
