It really won't. See Brazil. The president was elected with less support than that[0], and they are overhauling nothing. Don't think that things would be different in USA, don't fall to American exceptionalism. I recommend that you take a few minutes and honestly ask yourself what is different in the USA that would cause such a poor election to have a different consequence. A 10% will be taken as a sign of apathy, not of opposition, and as an opportunity to do whatever because people clearly don't care.
