Drucker's career in national politics started with the
1894 Dutch general election. This election was dominated by interior minister
Johannes Tak van Poortvliet's proposal to greatly expand suffrage, with candidates of different parties declaring themselves "pro-Takkian" or "anti-Takkian". As a pro-Takkian
Liberal, Drucker contested the election in the districts of
Leiden and
Groningen. In Leiden, he was defeated by the anti-Takkian Liberal Hendrik Johannes Bool, but in Groningen he unseated the anti-Takkian Liberal
Samuel van Houten, who had held the seat since 1869. Drucker took office as member of the
House of Representatives on 16 May 1894, and subsequently joined the Progressive-Liberal group. In 1901, he was one of the founders of the
Free-thinking Democratic League, and was the party's inaugural parliamentary leader. In the House, Drucker soon gained respect as a result of his knowledge, oratory skill, amiability, modesty and steadfast character. His interest lay less in politics than in legislative work, particularly regarding social legislation. He contributed to the 1901 Housing Act and the 1907 Employment Contracts Act, among others. In 1903, Drucker opposed interior minister
Abraham Kuyper's bill to criminalise strikes by railway staff and civil servants, arguing that where working conditions were unsatisfactory, the government should not deny workers the right to use their last resort of defence. Nevertheless, he rejected strikes as a political method. In the same year, the Free-thinking Democratic group in the House tabled a constitutional amendment aiming to introduce universal male suffrage, limited female suffrage and direct elections to the
Senate. The political work in the House of Representative did not interest Drucker for long, and he came into conflict with fellow Free-thinking Democrat
Dirk Bos, who more extroverted and practical in nature. Drucker was offered the ministership of justice in 1897 and in 1905, but he declined. In 1913, he retired from the House of Representatives as was elected to the
Senate for
North Holland, serving from 16 September 1913 until his death on 5 September 1917. ==Private life==
