According to AZ Central, McCain dismissed criticism over the tactics the Republican Establishment used to get black Democrats to cross over and vote for Cochran. 

Said McCain, "There are some people complaining that African-American voters voted. [But] I thought one of the major priorities of the Republican Party was to get all minority and ethnic voters out to vote for Republicans."

He described Cochran's "get-out-the-vote campaign" as "excellent," then talked about how he will face similar circumstances in Arizona and needs to work equally as hard if he runs again. "The key is you'd better pay attention, you'd better work hard, you'd better organize." He added, "And you'd better understand that there's a strong anti-Washington/anti-incumbency sentiment out there, which is justified and you've got your work cut out for you."
