Congressional Democrats applaud Mexican President Felipe Calderon after he endorses practices that damage the U.S.

If you are winning, go with the status quo.

That's what Mexican president Felip Calderon did this week. The question is, why did congressional Democrats give Calderon a standing ovation? Was that because the U.S. is losing, and further decline will hasten the day when free enterprise and free markets, institutions that many of the Democrats deplore, are finally tossed aside in favor of government by the biggest donors to their campaigns?

The most important relationship between Mexico and the United States is economic.

Mexico exports poverty and low skills to the United States.

The United States, in turn, supplies education and welfare benefits to imported Mexicans who, in turn, export billions of dollars to Mexico. In 2007, those remittances totaled $23.98 billion. In 2008, the total rose to $25.145 billion.

While the figure for 2009 is not yet in, it is expected to fall to about $21 billion. Hard times are at hand in Mexico.

If Arizona's new immigration law deters illegal border crossings into Arizona, the number of illegal aliens sending remittances to Mexico might fall off on a lasting basis. Emulation of the Arizona law by other border states could put a real crimp in Mexico's profit from illegal border crossings.

That's why Calderon spoke with such urgency about the awfulness of the Arizona law. President Obama appeared to agree with him, which was not surprising for a chief executive who has little good to say, but much to rebuke, about the land he has chosen to misgovern while awaiting his chance to govern the world.

Obama breaks with tradition by siding with Mexico's president against Arizona's governor

Undeterred by the lack of success so far of the Obama Doctrine (apologize for America to foreign leaders, and if that doesn’t work, bow), President Obama today took the unprecedented step of publicly siding with Mexico against the state of Arizona. President Obama did this while standing next to the visiting President of Mexico, Felipe Calderon, and while addressing Mexican journalists in the Rose Garden of the White House.

President Obama repudiated Arizona’s anti-illegal immigration law in this public act, and by doing so he waved away not just centuries of tradition that domestic disputes end at the water’s edge—that we’re all American, whatever our differences may be—but also common sense and, well, national decorum. Whatever the merits and demerits of the Arizona Law, President Obama had no business agreeing with a foreign leader against the elected government of Arizona and 70% of the people in that state who support the law.
