Since the Senate began to hold hearings on SCOTUS nominees, there have been two times the Senate did not hold hearings, report the nomination and hold a vote.  Harriet Miers was interviewed via questionnaire by the Judiciary Committee and they hated her answers.  She was never given a hearing.  Her nomination was withdrawn without a hearing.  Homer Thornberry, nominated by Johnson, had hearings but the Judiciary Committee never reported him out and his nomination was withdrawn.
