For me, the whole thing is rather simple. I will never vote for anyone who hitches their wagon to the Democrat mule, whether it be dog catcher or president.
Not that I have some great love for the Republican party either, as I have voted for candidates in various races that were tied to the Iowa Party, the Alaskan Independence party, the Libertarian Party, the Constitution Party, and a few Republicans.
The Democrat party sold out 58,209 of my dead brothers and sisters in arms in the Viet Nam escapade, not counting the wounded. They sold out 21 million S. Vietnamese, of which about 800,000 fled by boat and even the UN estimates those that died miserably at sea was in the 200,000 - 400,000 range. Many had what little money they carried taken from them by pirates, many of the women were raped. One S. Vietnamese officer I knew of was forced into one of the Communist "reeducation camps" and forced to live in a bamboo cage in the hole in the ground for 3 years. When he finally got released, he fled via the boats with his wife and daughter. His wife was raped, his daughter was taken by pirates. Eventually he and his wife made it to the U.S. and they have done well. Amazing story.
All because they would not honor the treaty we had with Viet Nam. President Ford begged the Democrat controlled legislature to release the funds and munitions so the Vietnamese could defend themselves. Many Vietnamese artillery units were down to 1 round per gun per day. There was no spare parts, ammo, fuel etc for mechanized and air force equipment. The Democrat controlled congress had cut off all funding and munitions in 1974. Saigon fell in April 1975. I saw it. I lived it.
Even with our troops in Iraq, the usual suspects from the Democrat party condemned the troops involved in the major battles of Mosul, Tekrit, etc and said publicly they would lose. Out and out treason. Pelosi, Reid, Schumer, etc.
The Democrat Party has been the main motivation behind abortion rights. So they are guilty of over 61 million infant deaths since 1973. More than the known children killed by Hitler, Stalin, and Mao combined.
And having given all of the 1970's to protecting this country from Socialism / Communism, it is appalling to the see the Democrat party primarily populated with socialists / communists. And worse, that many in this country actually support such as AOC, Sanders, etc.
And some think that Trump is the worse thing to happen to this country. Such is the historically illiterate.
