Washington (CNN) Nearly half of US voters say the Senate should not vote to confirm Brett Kavanaugh to the Supreme Court in a poll released Monday.

The poll , from Quinnipiac University, showed opposition to the Supreme Court nominee has grown since last week's hearing before the Senate Judiciary committee where Kavanaugh defended himself against accusations of sexual misconduct.

Overall, 48% of respondents oppose Kavanaugh's confirmation, up from 42% who said the same in early September. Opposition among female voters is higher, with 55% opposing his confirmation, a jump from 47% before the hearing.

The views of male voters were largely unchanged, with 40% now opposing his confirmation versus 37% in September.

The poll also found voters are finding Kavanagh's accuser, Dr. Christine Blasey Ford, more credible after her emotional testimony before the Senate Judiciary committee where she alleged Kavanaugh sexually assaulted her during a high school party in the 1980s. Forty-eight percent of voters say they tend to believe Ford, while 41% believe Kavanaugh.
