Cindy McCain recorded a video message for Tuesday's Democratic National Convention, paying tribute to an "unlikely friendship" forged between former Vice President Joe Biden and her late husband, Sen. John McCain (R-Ariz.)
Why it matters: Cindy McCain, who describes herself as a "Reagan conservative, a little more liberal on some social issues," is the latest Republican to lend her voice to the Democratic convention, after four conservatives including former Ohio Gov. John Kasich spoke Monday.
