Do you think it is appropriate for retired military leaders to publicly endorse political candidates?

NO---But---than again---generals will be generals.

Not really. This election cycle has seen retired senior military service members endorse candidates on both sides of the political spectrum, so they've basically negated each other. Since it is basically a draw, they've politicized the military for no measurable political benefit for either party. The only loser out of the whole deal is the military as it may lead to significant distrust between our elected officials and the military as a whole.

Why not? Do they lose their rights because of service? CPT (Join to see)

Absolutely, once retired, we have as much right as anyone else to support politically who we chose. I am proud of my service and would mention It, if asked, in any endorsement.

I believe President Harry Truman, though a politician, said it best after Eisenhower was elected and thus denied Truman a second term. Truman stated he had been promoted to the highest american rank...civilian. As I recall, he never, from that point on, allowed anyone to refer to him as "Mr. President", just "Mister".
So it should be with Retired Officers. They have been promoted to citizen and have all the rights thereto while simply possessing special awareness and knowledge.

One they retire they are a normal citizen again as long as the uniform isn't worn there is no problem.

First Amendment right.

Welcome to the 1st amendment

Absolutely! You have every right to voice your opinion about anything you damn well please. Politics included.

Absolutely. As we serve we effectively have a "gag order" on us. We fought for the freedoms the other 99% take for granted on a daily basis. I feel when you are out, you've earned that right to publicly express your thoughts and endorsement.
