If it brought up rich Jewish bankers 70 years ago and only brings up rich bankers now, it's obviously less antisemitic now than it used to be. But in any case, you cannot use the name "Rothschild" to make the point that a Jewish person would have a disadvantage in an election - you could at most make the point that someone whose name brings to mind rich Jewis people might have a disadvantage. I think this is more properly construed as the basis of brazil's original objection.
