Why are Republicans siding against Law enforcement and Military on important issues?

We have heard from Arizona Law Enforcement as well as National organizations of Law enforcement agencies and it is virtually unanimous, they are all against the new law. Republicans however do not stand with the Police or Law Enforcement. They are now siding against Law Enforcement and the Military on Don’t Ask Don’t Tell with our top Commandeers and Chief of Staff all in agreement that Gays should now serve. 75% of the population also agrees. Does it seem these days that Republicans are out for themselves and that is all?
