My sister is a flaming lib too - voted for Obamao twice, and will vote for Shrillary. But that has zero effect on my political views, or my principles. Sorry, but worrying about Trump because of his sister's politics is not really sensible.
Remember your words if he appoints her to THE SUPREME COURT
Your sister isn’t a potential SC nominee (I presume). And most importantly, and ,RCs point is this: is the sister indicative of the type of person he would appoint to the court.
Because as much as many trumpeters scream about immigration being the most important consideration, SC picks are JUST AS important...if we get a couple of ginsbergs on the court this American experiment is over.
