It really depends on the type of help, and it depends on what kind of DUmmy they are (see the post about digging up Reagan's rotting corpse).
Moral support and advice? Sure, only if asked. Monetary? Very carefully. I had a friend, though not overtly political, I knew what her background was and it = Democrat. She needed just $300 to meet the tuition bill for her later-in-life associates degree. I was glad to help, and she paid it back.
Have a DUmmy BIL who was the classic case, I've mentioned him before, living in his car, drinking & gambling any money he did happen to scratch up. We said NO NO NO, causing a family feud. Anyway, he seems to have pulled his shit together, believe it or not.
