He was first elected to the House of Commons at the 1895 general election as Member of Parliament (MP) for Camborne, having unsuccessfully contested the seat in 1892. He was defeated at the 1900 general election, and failed to regain the seat at a by-election in 1903 after the death of his successor, William Sproston Caine.
At the 1906 general election, he was selected to stand as the Conservative candidate in Paddington North, where the sitting Conservative MP Sir John Aird was retiring and the local Conservative Association had found difficulty in selecting a candidate. However, his selection proved controversial, because Strauss was Jewish and the Liberal Party candidate Leo Chiozza Money was Italian, and a committee of objectors to "foreign" candidates was formed which persuaded Sir Henry Burdett to run as an Independent Unionist candidate. Although the constituency had at times been marginal, Paddington North had been held by a Conservative since its creation in 1885, but the split Unionist vote allowed Money to win the seat for the Liberals.
Strauss was selected again to contest Paddington North at the 1910 election, and faced a repeat of the previous opposition. However, the dissident 'League of Patriotic Electors of North Paddington' decided in the end not field a candidate, and at the general election in January 1910, Strauss won the seat, having campaigned on tariff reform. He was re-elected in December 1910.
At the 1918 general election, Strauss stood as an "Independent Labour" candidate and lost both the seat and his deposit, winning only 4.5% of the votes. He subsequently joined the Labour Party, but although he did not return to Parliament, his son George (1901–1993) also joined Labour and was an MP for 46 years, eventually becoming Father of the House in the 1970s and then a life peer. His other son Victor, a Lieutenant in the Royal Flying Corps was killed in action in 1916.
