They are only affecting Liberals and NeverTrumps who would not vote for Trump anyway.
Anyone who knows Trump, knows that he is the most pro-military pro-LEO President ever.
In fact, this is exactly why the Leftist chose this point to attack Trump. They attack on his strongest point.
This is like trying to convince the public that black is white and up is down.
They will only convince people who want to believe everything negative about Trump anyway, with or without any evidence whatsoever.
Liberal philosophy is to throw everything against the wall and see what happens. I have heard Trump called an anti-Semite more times than I can count, even though many in his own family are Jewish. When Trump is not being called antisemitic he is being called a Jew-lover who is in bed with Israel. Again, truth does not matter to the Left. Try one thing for while, if that doesn't work try the opposite thing. Try anything and everything. Why not?
