'Sa se puede!" Yes we can. They marched by the hundreds of thousands in Los Angeles, by the tens of thousands in Milwaukee, in Phoenix, in New York. Across the country, Hispanics dramatically entered what has been an increasingly ugly debate about immigration in this country.

Rep. Tom Tancredo is gaining national attention railing against undocumented immigrants. He wants them turned into felons, a wall built along our border to keep them out, police dispatched to send them home. He does not bother to tell us how he plans to transport 11 million estimated undocumented workers out of the country. Nor what will happen to the millions of their children who were born here and are American citizens.

Senate leader Bill Frist is doing his own Tancredo. Efforts by Senators Kennedy and McCain to fashion a compromise look likely to fail in the face of the furies. President Bush has offered an employers bill -- why does this not surprise? He'd increase enforcement at the border, but create a guest worker program so that employers could ship low wage immigrants in, so long as they promise to boot them out when they've finished exploiting them.

When employers brought slaves to America, few objected as long as they were prepared to work without wages and without rights. When they began to demand equal rights, all hell broke loose. No one minded when Mexican farm workers came to pick the crops, do the lawns, clean the houses. When they started to demand the right to citizenship, to vote, to organize -- the furor started.
