One act that I have always never been fond of and wished to be repealed is the Reapportionment Act of 1929 which limits the amount of members of the House to just 435. I've always found this to be rather undemocratic method as it does not take into account the growth of the United States, which has doubled in size since then, and will always limit the smaller states such as Wyoming to just one congressmen, not allowing them the chance to have a broad and diverse federal representation.
So, assuming that events roughly play similar to OTL, which time period has the best chance of repealing the act, which President would have been most in favor, and which party would it benefit the most?
