Stein was firstly Liberal candidate for the
Dover division of Kent at the 1922 General Election. This was a safe Unionist seat that a Liberal had not won since 1857. The Unionists held the seat. He was then Liberal candidate for the
Kensington North division of London at the 1923 General Election. This was a Unionist seat and not a good prospect either as the Liberals had come third in 1922. However, he did manage to increase the Liberal share of the vote; He did not contest the 1924 General Election. He was then Liberal candidate for the
Bermondsey West division of London at the 1929 General Election. This was a Labour seat that the Liberals had last won in 1923. He might have entertained hopes of regaining the seat, however the Unionists who had not run a candidate in 1923, chose to intervene. As a result, Labour comfortably held the seat; He did not stand for parliament again. ==Publications==
