a voice vote. He also failed to win support for a statement that condemned both left- and right-wing extremism without naming any organizations, which lost a standing vote by a two-to-one margin. Both of Romney's positions were endorsed by former President Dwight Eisenhower, who had an approach to civic responsibilities similar to Romney's. As the convention concluded, Romney neither endorsed nor repudiated Goldwater and vice presidential nominee William E. Miller, saying he had reservations about Goldwater's lack of support for civil rights and the political extremism that Goldwater embodied. For the fall 1964 elections, Romney cut himself off from the national ticket, refusing to even appear on the same stage with them and continuing to feud with Goldwater privately. He campaigned for governor in mostly Democratic areas, and when pressed at campaign appearances about whether he supported Goldwater, he replied, "You know darn well I'm not!" Romney was re-elected in 1964 by a margin of over 380,000 votes over Democratic Congressman Neil Staebler, despite Goldwater's landslide defeat to President Lyndon B. Johnson that swept away many other Republican candidates. Romney won 15 percent of Michigan's black vote, compared to Goldwater's two percent. In 1965, Romney visited South Vietnam for 31 days and said that he was continuing his strong support for U.S. military involvement there. During 1966, while son Mitt was away in France on missionary work, George Romney guided Mitt's fiancée Ann Davies in her conversion to Mormonism. Governor Romney continued his support of civil rights; after violence broke out during the Selma to Montgomery marches in 1965, he marched at the front of a Detroit parade in solidarity with the marchers. In 1966, Romney had his biggest electoral success, winning re-election again by some 527,000 votes over Democratic lawyer Zolton Ferency (this time to a four-year term, after a change in Michigan law). His share of the black vote rose to over 30 percent, a virtually unprecedented accomplishment for a Republican. By 1967, a looming deficit prompted the legislature to overhaul Michigan's tax structure. Personal and corporate state income taxes were created while business receipts and corporation franchise taxes were eliminated. Passage of an income levy had eluded past Michigan governors, no matter which party controlled of the legislature. Romney's success convincing Democratic and Republican factions to compromise on the details of the measure was considered a key test of his political ability. The massive 12th Street riot
