so what do you think that the right barometer is for a guy like trump? well, the 50% threshold is a good barometer for a one-on-one race or general threshold con context, but in a crowded field for the republicans, but as the delegate rules are set up, 42% would be quite sufficient for him. thank you, david chalian. sara? meanwhile, trump is targeting a new ad to slam president biden and the economy. it is the second trump/biden comparison ad they have put out in the last couple of week, and now, we are following this, and i m no political director like david chalian, but why should donald trump bother when he is clear and away the republican favorite at this point?
