Mudge, a White Namibian, was born in Otjiwarongo, Otjozondjupa; he is the son of Republican Party founder Dirk Mudge. The younger Mudge was a founding member of the Republican Party in 1977; the party joined the Democratic Turnhalle Alliance (DTA) in the same year, and Mudge held a seat on the Khomas Regional Council from 1992 to 2003 as a member of the DTA, representing Windhoek West constituency. In mid-2003 Mudge launched an effort to revive the Republican Party as an independent organization, and he resigned from the Regional Council on June 30, 2003. DTA President Katuutire Kaura denounced Mudge's move to separate the Republican Party from the DTA, saying that Mudge acted unilaterally and illegally, and he said that Mudge had "expelled himself" from the DTA through his actions. Kaura claimed that Mudge wanted to create a party solely for "previously advantaged" minority Namibians. Mudge became the President of the Republican Party, as well as a member of its National Executive Committee, in 2003.
