Cindy McCain is John McCain's wife. Some people think she is an ugly shrew with a face that plastic surgeons botched. Sometimes she talks and says stupid things. There's been some trouble over Mother Teresa.
Dubya's surrogates, during the ill-fated 2000 US Presidential Republican primary campaign, accused her of being a drug addict. By association and the Bush-Talking-Is-Lies-No-Matter-What Corollary, this is not true.
Fortunately the American people had enough sense to vote against Cindy's husband. She's not so important now.
