The first test you need to apply in the first phases of analyzing a politician is their stance on jews. I am not demanding full 1488, but i need to see that they have distanced themselves from jewish influences as much as possible. If they are like trump and have multiple jews marrying into their families, if they have a picture of themselves on the wailing wall, if they call israel a great ally, if they are advised on handled by jews, then hard pass on them.
