Is it hypocritical that Taylor Swift did not speak out all or use her influence during the election, but tweeted that she supports the Women’s March?

It is not Hypocritical at all. Everyone has a moment when they feel the need to participate in causes they feel strongly about. Figures who are in the public eye often gloss over many public events, so they don’t potentially alienate their fans.
Taylor Swift on Feminism
Ms. Swift is very open about her ability to influence people, and restrains from political controversy intentionally; She does not want to exert undue influence on an election, or have her fans change their opinions because they want to vote like her, and not on issues.
Some fans “called her out” on this tweet, Stating that “you don’t get to pick and choose only when feminism benefits you”.
Despite fans and tabloids clamoring for more Taylor Swift, it is commendable that she tries to keep a sense of propriety and privacy on public issues, after all, she is a top shelf entertainer, and not a political hack.
