Of course. Does their voter base strike you as people who give two shits about their own well being?
They run on spite. They don’t want to win- they just want you to lose. And they’ll pretend to believe whatever might have to be true to make them feel like you have.
Sure, if “caring about their own well-being” = “maintaining their very fragile shitty worldview and trying to hide their pants-wetting cowardice about anything unfamiliar,” sure.
