Not in modern America. Americans, for good reason, have a kneejerk negative reaction to the words "war in the middle east". A war with Iran before November would seal Harris's fate.
i think it is more likely that the opposite would happen. Anyone with two brain cells understands that there is nothing to gain for the US from it. Maybe for the MIC but certainly not for the average American who will have to deal with high oil prices, recession and possibly his son coming back in a coffin.
