President Donald Trump may be getting too overzealous in waging the culture wars, according to a new poll that shows his approval rating plummeting.

Just 42% of respondents in the Reuters/Ipsos poll that concluded Monday approve of how Trump is handling his job — the lowest mark since began his new term Jan. 20, the six-day survey showed.

Trump stood at 43% approval three weeks ago and enjoyed a 47% approval rating when he was inaugurated.

Americans believe Trump has been too aggressive in seeking to punish Harvard and other universities deemed to be liberal, the poll found.

Just 28% of adults said their president should withhold funding from universities they disagree with, while 58% said their president should not take that action, the poll found.

Respondents were also uneasy about the president overhauling the Kennedy Center board and installing himself chairman.

Only 14% said their president should control national museums and theaters compared to 66% who said presidents should not assume control of those institutions.

A strong majority of Americans also disagreed with Trump disobeying the court order to facilitate the return of Kilmar Abrego Garcia, who was mistakenly deported to a brutal prison in El Salvador.

Of the more than 4,300 U.S. adults polled, 83% said a president should obey a court order they disagree with, while 13% said the president should not obey such an order.

Americans are also adamant about Trump not seeking a third term.

Although the Constitution is clear that Trump cannot be elected president again, he has floated the idea of running.

Americans want him to stop thinking about it, according to the poll.

About three-fourths of respondents said they don’t want Trump seeking a third term.

A majority of Republicans — 54% — also said Trump should not run again.
