Hader was first elected to the Assembly in 1885 from the 8th Milwaukee County Assembly district (the 8th, 11th and 14th Wards of the City of Milwaukee), receiving 2,206 votes to 1,794 for Republican John L. Burnham and 29 for Prohibitionist 0. 0. Storle (Democratic incumbent John Fellenz was not a candidate). He did not run for re-election, and was succeeded by Populist Benjamin Charles Garside.

In 1902, he was again elected to the Assembly, from what was now the 11th Milwaukee County district (the 11th Ward of the City of Milwaukee), with 1,139 votes to 1,112 for incumbent Republican Herman Pomrening, 1,065 for Socialist Edmund T.
