because it said that since the states had formed the national government, state power hould be greater than federal power. ... Favored the idea of a weak president and a strong Congress.

i would say that the politicial parties from state to state varies.

the  equal rights amendment  (era) states: "equality  of  rights  under the law shall not be denied or abridged by the united states or by any state on account of sex." congress first introduced the era in 1923, but the campaign for ratification took off in the 1960s during the  civil rightsmovement.
