At least, no-one at the convention would ever imagine it. Others are imagining it with salivating malevolence. The Washington Post's Harold Meyerson wrote on September 3:
...the Republicans now more than ever are the white folks' party, the party that delays the advent of our multicultural future, the party of the American past. Republican conventions have long been bastions of de facto Caucasian exclusivity, but coming right after the diversity of Denver, this year's GOP convention is almost shockingly — un-Americanly — white.
"Un-Americanly"? So whites are not merely to be a minority, they are to be deprived even of the name of the country they founded, built up and were 90% of until 1960.
What, then, would define "American"? We can be sure Meyerson is ready to tell us. (Ask him).
We can also be sure that Sarah Palin's speechwriters - and who knows about Ms. Palin herself - would not listen.
