The front of the Sunday Week in Review is dominated by business columnist-reporter David Leonhardt's "The Border And The Ballot Box ," his slanted essay on anti-immigration crusades then and now. The accompanying drawings give the debate the feel of a prison camp, with Americans as prison guards and potential illegals as prisoners, and thearchiveillustrationson the jump page include a drawing of a burning church, bearing the caption:
Anti-Catholic - Burning of St. Augustine Roman Catholic Church in Philadelphia, 1844. As immigration soared, so did nativist reaction.
Another archive illustration is captioned:
Anti-Chinese - An illustration of a massacre published in Harper's Weekly, 1885. Chinese laborers were attacked by white coal miners.
Get the hint? If you are against illegal immigration today, you are akin to "nativist," violent, racist mobs from over a century ago.
Throughout the long piece, Leonhardt blithely refers to anti-immigration movements, without bothering to clarify that what most protestors oppose is illegal immigration, not immigration per se.
On June 7 of last year, a bill to overhaul the nation'simmigration system - a bill supported by President Bush and the Democratic leaders of Congress - died in the Senate. It died mostly because of grass-roots opposition, and its downfall appeared to serve as an announcement of the issue's new political potency. For much of 2007, immigration seemed certain to play a dominant role in the 2008 presidential campaign.
The backlash even had a familiar feel to it. In the last few decades, the country has experienced its fourth great immigration wave. Each of the other three - in the 1850s, 1880s and early 1900s - also caused a political reaction, the first and most famous being the rise of the Know Nothing movement. History looked as if it would repeat itself, albeit in a milder form, this year.
And so it has. It's just that the lessons of the past aren't quite what they first appeared to be.
There is, however, one more historical parallel to consider: as a political matter, immigration probably won't go away on its own. The anti-immigration movements of the past may not have created presidents, but they did change the country. The Chinese Exclusion Act helped cut the immigration rate by more than 40 percent at the close of the 19th century. The Nativist movement of the 1910s and 1920s had even more success passing laws to reduce the flow.
Unlike those earlier immigration waves, the current one includes a large number of illegal immigrants, which creates its own political dynamic. The subject also plays into the economic anxiety of today that stems from decades of slow wage growth and is now aggravated by the possibility of a recession. Perhaps most important, this immigration wave could turn out to be the biggest of them all. Last month, the Pew Research Center  reported that the percentage of Americans born overseas would break a century-old record sometime before 2025, if current trends continued.
It's hard, in fact, to see how a single 2008 Republican candidate benefited from anti-immigration rhetoric. All the while, Mr. McCain's campaign bus was being followed around the early-voting states by a white van called the "Amnesty Truth Express." Outside his Florida headquarters in West Palm Beach, a few days before he won the primary that established him as the clear front-runner, the van displayed a sign reading, "McCain Equals Amnesty."
How could Mr. McCain's resurgence happen only six months after Americans deluged members of Congress with phone calls opposing an immigration bill that would have provided a path to citizenship for many people in the country illegally? And how could it happen when several states, including Arizona and Colorado, have recently implemented laws to make life harder for these immigrants? The country's previous backlashes offer something of a guide.
Check out the loaded language:
The Nativist reaction of the early 20th century started with a similar virulence. In the aftermath of World War I, "there was just this fear that millions of people were going to pour in," said Mae Ngai, a Columbia University  historian. "You could read the discussion from the 1910s and think you were looking at something from today, if you just took out 'Italians' and put in 'Mexicans'"
Anti-immigrant sentiment probably did help Herbert Hoover beat Al Smith - a Catholic, like many immigrants at the time - in 1928. But after Congress overwhelmingly passed new immigration restrictions in 1924, the main political fight over immigration occurred not between the parties, but within the Democratic Party , with those who wanted to embrace the Ku Klux Klan  battling those who did not. Franklin D. Roosevelt  was in the latter group.
Mr. Rauchway, the historian, argues that the ultimate failure of anti-immigrant politics is part of a larger failure of class-based politics in the United States. Running against the rich - or the poor - has rarely worked in this country. Instead, immigrant-bashing has been most successful when it tapped into broader racial fears, as it did in both the 1850s and the 1920s. Notably, the economy was booming in the '20s.
"As it becomes less and less acceptable to be racist," Mr. Rauchway said, "immigration is not going to be as politically effective."
Polling data supports this argument. In a New York Times/CBS News poll conducted last May - in the midst of the debate over the immigration bill - 57 percent of respondents said that most recent immigrants contributed to this country, up from 34 percent when the question was asked in 1986. Only 28 percent in last year's poll said that most immigrants caused problems, down from 44 percent in 1986. The Gallup Poll also shows increasing sympathy for immigrants.
Leonhardt insists more immigrants are both desirable and inevitable, implying that concern about immigration is simply misplaced nostalgia.
No matter how it happens, the country will almost certainly need an influx of new arrivals in coming decades. The baby boomers are about to start turning 65. Someone will have to take their place in the work force - and help pay their Medicareand Social Security bills.
After a year of political whiplash, it seems safe to conclude that the anti-immigration fervor was never as bad as it seemed but isn't permanently gone, either. As ever, we Americans like to say that we live in a nation of immigrants. But we are also prone to believing that the last great immigrants were the ones who arrived decades ago. The country can never quite make up its mind how open it should be.
