[单项选择]You might think they would have learned their lesson by now. At the end of 2005 Republicans in the House of Representatives passed a bill that cracked down on illegal immigration, while doing nothing to regularise the position of the 12m or so people, mostly of Hispanic origin, who were living and working inside the United States without the proper papers, or to create a mechanism for allowing in people from Mexico and other southern neighbours to work with temporary permits. The bill never became law, but its one-sided nature helped stamp the Republicans (92% of whom voted for it in the House) as an anti-immigrant party. In April 2006 Latinos organised a day of protests in more than 100 cities; more than 500,000 people marched in Los Angeles alone. In the 2008 election 67% of Hispanics voted for Barack Obama.
Now it is all happening again. Until now, the detection of illegal immigrants has invariably been a matter for the federal authorities.
