He got his start in political organizing right here.
http://bnfp.org/neighborhood/Lemann_Rove_NYM.htmThe story of Edgeworth and Rove is a well-burnished legend within a very small circle-well burnished enough that just saying "Lake of the Ozarks" is enough to evoke it. The circle is made up, of people connected with College Republicans, a group tight enough (it became an independent organization in 1971) that all its significant figures at least know one another's names. Theirs is a subculture that took form in the mid- to late sixties, at a time when what was officially going on in the United States was a great uprising of rebellious youth and a flowering of liberal politics. The College Republicans were young people who believed that the coming thing was a resurgence of the political right. They felt this so strongly, and loved politics so much, that they devoted a ruthless, all-consuming effort to gaining advantage in a small student organization that today seems a little eccentric. The history of College Republicans is like that of a left-wing group, full of coups and counter-coups and intrigue. And the most College Republican of College Republicans was Karl Rove.
Rove had come out of nowhere-to be specific, Utah, from a nonpolitical and not very well-established family that he didn't talk about much. As a seventeen-year-old, Rove made the leap beyond high-school politics by volunteering in a United States Senate campaign. In 1969, at the University of Utah, he signed up for the College Republicans, and showed enough promise that the organization dispatched him to Illinois the following year to work as a campus organizer in the unsuccessful United States Senate campaign of Ralph Tyler Smith, who had been appointed to the seat of the Senate's Republican leader, Everett McKinley Dirksen, after Dirksen died. This amounted to hitting the big time, because Illinois was the most active College Republican state. In 1971, Rove became a protege of Joe Abate, the College Republican chairman, who hired him as the organization's national executive director, a position that paid very modestly.
