There is no doubt that the contemporary Republican electorate contains some out-and-out bigots, just as the Democratic electorate contains people who hate others on the basis of class. These very real prejudices occasionally erupt into public expression, whether in remarks about Jews over the years by Jesse Jackson and Al Sharpton or in shocking signs at tea party rallies.
But most conservatives have been less concerned with the "hardware" of people's race or ethnicity and more concerned with the "software" of their values or culture. This is why the white Protestant core of the modern conservative movement has not merely integrated Catholic "ethnics" but also rallied behind the Irish American William F. Buckley and the Italian American Antonin Scalia. Jews, women and Hispanics have been similarly integrated into both its ranks and leadership; indeed, many white conservatives swoon when members of minority groups proudly share their values. This explains why, in the 2008 campaign, conservatives were at least as roused by Obama's ties to the white former radical William Ayers as the black Jeremiah Wright, both of whom seemed to make a living out of damning America.
Liberal interpretations that portray modern conservatism as standing athwart the "rights revolution" of the 1960s are hard pressed to explain the growing number of minority and female candidates favored by the conservative rank and file. Marco Rubio, Nikki Haley, Susana Martinez, Brian Sandoval, Tim Scott, Ryan Frazier, Raul Labrador and Jaime Herrera are GOP nominees for the Senate, governorships and the House because Republican voters preferred them over their white opponents. Allen West in Florida and Jon Barela in New Mexico were the consensus GOP choices to run for competitive House seats. Many of these candidates are well-positioned to win their races and help change the public face of modern conservatism.
