By midmorning Cao was interrupting an interview to take a call from former House Speaker Newt Gingrich, who offered good wishes and, Cao said, counseled him "to reach out to the African-American community." Cao said Gingrich offered to act as a go-between.
Now, part of me is sympathetic: It's hard to admit to yourself that a large swath of the American population finds you loathsome. But still, some self-awareness is in order here. Pat Buchanan seems reasonably aware that he is not a popular figure amongst Jews (he doesn't think it's just, but he does acknowledge it). Gingrich can reasonably be expected to know he is not the most popular figure amongst American Blacks.

On Monday his wife, Hieu Phuong Hoang, who goes by Kate, celebrated Cao's victory by calling Walgreens, where she worked as a pharmacist, and quitting her job.
