Mitt Romney's campaign had a message Tuesday for those who would try to stop his forward momentum to the Republican presidential nomination — he's got this.

Oh, and Tuesday's contests really don't add up to much of anything really.

The Susan G. Komen for the Cure foundation has been in the news because of its clash with Planned Parenthood Federation of America.

But another aspect of Komen's activities hasn't received much attention: Komen's position on research using human embryonic stem cells.

Despite raising millions of dollars for breast cancer research, Komen hasn't funded any of this work, prompting questions about whether that decision is rooted in politics.

It's no secret that some of the tastiest snacks around — potato chips, french fries, and processed deli meats — are terrific vehicles for salt. Without salt, they'd be bland, too starchy, or just plain dull.

But would you guess that the white bread on your turkey sandwich could be delivering as much or more than the turkey — up to 400 mg of sodium, or about one-third of the daily recommended limit for 6 of every 10 adults?

For an election that shouldn't matter on paper, Missouri's primary on Tuesday may carry a lot of weight.

The state's Republican electorate tends to be both populist and conservative. That could give former Pennsylvania Sen. Rick Santorum, who has campaigned in Missouri the most – and the most recently – among GOP presidential candidates the chance for a strong showing.

Do you know the way to famously reclusive Bolinas?

If so, and you stop in at Smiley’s Saloon this Friday, you can hear the Blind Willies. This Bay Area band says its music is “gospel revised by thieves, pimps, poets, losers, children, and malcontents.” They also play the blues.

Music starts about 9pm . But remember, this is Bolinas, so be patient. 

In 2004, after an extensive review, the Food and Drug Administration issued a strong warning to doctors who prescribed antidepressants to teens and children.

Antidepressants, the FDA said, appeared to increase suicide among kids and teens. Doctors needed to be careful. The FDA even mandated that a "black-box warning," the strongest type, be placed on antidepressant packaging.

The cholera outbreak in Haiti is currently the worst ongoing episode in the world.

Over the past 15 months, it has sickened more than half a million people and killed roughly 7,000. The bacteria has now spread throughout the Caribbean island, and medical experts say it will be around for years to come.

Partners in Health, a Boston-based nonprofit, is planning to launch an unprecedented cholera vaccination campaign to try to curb the outbreak — but it faces many challenges, including a shortage of the vaccine.

There's no waiting in line at O'Fallon City Hall. A half-dozen election volunteers have been eagerly hoping that more people will turn up for Tuesday's Republican primary.

After five hours, they've seen a grand total of 33 voters. Normally, the City Hall precinct gets about 250 people to turn out for a primary.

"We haven't had many," says Vince Scully, a retired printer and election official. As for a late rush in the evening, he says, "We won't have that today."
