To date, some 1 million non-Mexicans have entered the U.S. through Mexico, of which about 700,000 have disappeared, according to a report in the Dallas Morning News. No one knows how many might be terrorists, though rough estimates are that about 70,000 of those non-Mexicans are Saudis between the ages of 18 and 34. Ponder that as you abhor racial profiling and replenish your stores of duct tape.

Now, if you were Sen. Hillary Clinton and were, you know, adamantly against illegal immigrants, you might do everything in your considerable power to tighten our borders. Instead, one week after the London bombings, Clinton voted against amendments to the Department of Homeland Security spending bill that would have paid for more border agents and more detention beds in fiscal 2006.

Some who voted against the amendments expressed concern that those spending increases were predicated on cuts to first-responders, such as police, firefighters and EMTs. One could argue reasonably that the real first-responders are the agents who keep the bad guys out in the first place, but let's move on.

More telling than a particular vote may be Clinton's mid-July speech to the National Council of La Raza, a Hispanic human rights organization. Speaking to thunderous applause, Clinton mentioned nary a word about immigration and all but launched into a hat dance while pushing every hot button near and dear to Hispanic (and especially Mexican) hearts.

She promised improved education and health care (hard to believe, I know) as well as help with lead paint and childhood asthma and teen acne and bad breath. OK, I'm joking on the last two, but it's still early. Meanwhile, she did vow support for the DREAM Act (Development, Relief and Education for Alien Minorities Act), which, if passed, would guarantee in-state college tuition rates for the children of illegal immigrants, as well as amnesty to some 65,000 illegal immigrant students who graduate from U.S. high schools each year.

DREAM is a nice idea if you're in a nanny frame of mind. But if you're serious about national security, then you're serious about illegal immigration. And if you're serious about illegal immigration, then you don't reward illegal immigrants with expensive promises while failing to make good on pledges to keep illegal aliens out.

And if Hillary Clinton is serious about being president of the United States, she'd better make up her mind.
