30. THE MELTING POT FREEZES OVER
In April, Arizona Gov. Jan Brewer, a Republican who took over Homeland Security secretary Janet Napolitano’s old job mid-term, signed Arizona SB1070. The controversial anti-immigration law requires all immigrants to carry alien registration cards at all times, and authorizes police to demand papers from anyone appearing reasonably “illegal.” Brewer's law alarmed civil libertarians and immigration activists, but was a hit with Arizona voters, who overwhelmingly elected her to a full term in November 2010.
