1. Paying politicians help the Jewish community is a well established tradition. In many countries these were mere “gifts” (what today is called a bribe). In America, they take the form of political contributions (giving a politician money for living expenses would probably be a bribe).
2. Given that many of the Democratic candidates have positions that would probably be very detrimental to the frum community, it isn’t hard to understand why many frum Yidden would support Trump.
3. If one considers this money could be spent a lavish simachas, expensive houses, or fancy vacations, it seems it is a reasonable expense. Paying off friendly politicians is a worthy cause. Of course supporting full time Torah scholars and supporting the poor in our own community (often the same) is probably a better defense against hostile government policies, but what can’t expect everyoneto be on a high enough madreiga (level) to undertand that.
