When it comes to close political races, the recent Gold Standard in the U.S. is the 2000 presidential vote in Florida.

So we were wondering how last night's result in the Iowa Republican presidential caucuses compares to that famous hanging-chad contest between George W. Bush and Al Gore.

Let's walk through the math:

The American political system — as corny, eclectic, chaotic and screwed up as it is with its straw polls, caucuses, primaries and contested elections — somehow gets the job done time after time.

It's weird, really: In this country that celebrates unity and national spirit, a president is chosen via quirky, jerky state-by-state (sometimes precinct-by-precinct) methods. In this society that seeks perfection, the leader is selected in a painfully imperfect process.

But, to paraphrase the old saw: Our funky form of democracy may just be the least worst way to govern.

Mitt Romney and Rick Santorum finished virtually even in Iowa's caucuses Tuesday, but after Rep. Michele Bachmann's sixth-place finish, she announced Wednesday that she is suspending her campaign.

A Catholic bishop in California has resigned his post after revealing in December that he has two children.

"The Vatican announced the bishop's resignation Jan. 4 in a one-line statement that cited church law on resignation for illness or other serious reasons," reports the Catholic News Service from Vatican City.

Pope Benedict reportedly accepted the resignation of Gabino Zavala, an auxiliary bishop for the San Gabriel Pastoral Region, in December.

If a heart attack sends you to an American hospital, you'll probably go home after only two or three nights. That's faster than virtually anyplace else in the world.

But your chances of needing to go back into the hospital within the next month are also higher than they are for heart attack patients in 16 other countries. That's the finding from a Duke University-led study in this week's JAMA, the Journal of the American Medical Association.

If the grocery bill hurts more now than it used to, you're not alone. The cost of staples like ground beef, chicken, eggs and potatoes has spiked over 10 percent in the past year, three times the cost of inflation overall.

Ironically, if you were trying to be thrifty by eating at home instead of eating out, you probably felt it most.

Last year was a very good year for the German automaker Volkswagen, but 2012 could be even better.

Sales for Volkswagen Group's brands — including Audi, Bentley and Lamborghini — increased by 20 percent in the U.S. last year. For the Volkswagen brand itself, sales rose 26.3 percent. And if things continue to go Volkswagen's way, it could become the No. 1 carmaker in the world.

Minnesota Rep. Michele Bachmann announced Wednesday that she is suspending her campaign for the Republican presidential nomination. The conservative provocateur finished a disappointing sixth in Tuesday's caucuses in Iowa, with just 5 percent of the vote.

"Last night the people of Iowa spoke with a very clear voice," Bachmann said at a mid-morning news conference in West Des Moines. "So I have decided to stand aside."

Though he said last night that he would go home to reassess his bid for the presidency — a signal that he might drop out of the race — this message just popped up on the personal Twitter page of Texas Gov. Rick Perry:

"And the next leg of the marathon is the Palmetto State...Here we come South Carolina!!!"

President Obama will use what's known as a recess appointment to name Richard Cordray the head of the country's new consumer watchdog agency.
