If there is a boogey man in the Ohio presidential sweepstakes, it's China. According to Bloomberg, the Democratic and Republican presidential candidates have aired nearly 30,000 ads that mention trade with China, many airing in the key swing state of Ohio.

Talk of a Tomato War is simmering in agricultural circles, after the U.S. Commerce Department issued a report Thursday that recommends ending an agreement on how fresh tomatoes grown in Mexico are sold in the United States. The issue could create an expanding trade conflict; Mexican officials have said they would retaliate to defend the tomato growers.

The western Afghan city of Herat has become a thriving hub for the money exchange business, a consequence of geography and politics. Money-changers throng the currency market carrying thick stacks of Iranian currency, much of it brought in by the hundreds of thousands of Afghan workers who earn their living in Iran.

While the stacks of crisp 100,000 rial notes that money-changers bring to the market might look like a small fortune, the 10 million rials in each of these stacks is worth less than $400, because the Iranian currency recently lost more than half of its value.

In an attempt to put down the insurgency in Afghanistan, the international community has spent millions to try to reintegrate former Taliban fighters and other militants back into society.

So how well has it worked?

Critics like Kate Clark of the Afghanistan Analysts Network say many militants use these programs to gain access to arms and money, without necessarily changing their ways.

After inadvertently airing live coverage of a car chase that ended with a man's suicide, Shepard Smith of Fox News has issued an apology to viewers of his show. The incident occurred as the cable network carried a live feed of a man fleeing police on the interstate west of Phoenix.

In the footage, the man abandoned his vehicle and began running across a field, before pulling out a gun and shooting himself in the head. Despite being filmed from a helicopter hovering above the scene, the footage was graphic enough to prompt immediate yelling in the Fox News studio.

It might seem counterintuitive, but the man running against Republican Linda McMahon in her second attempt at becoming Connecticut's first female senator wants this race to be all about women.

Democratic Rep. Chris Murphy released an ad this week, hammering McMahon's stance on women's health and reminding voters of McMahon's former role as CEO of World Wrestling Entertainment.

Despite international condemnation, Pakistan's railways minister says he isn't backing down from his $100,000 bounty offer to anyone who kills the maker of the anti-Islam film Innocence of Muslims.

Ghulam Ahmed Bilour, the slight, silver-haired minister, says he was angry when he saw the video and that he's a man of great faith, passionately devoted to the Prophet Muhammad.

An oddity of U.S. presidential politics is that candidates and their campaigns spend nearly all their time telling voters how superior they are to their rivals in virtually every area: the wisdom of their policy proposals; the soundness of their characters and judgments — everything, really.

Except for debating.

It's the old game of setting the bar high for your opponent and lower for your candidate, of course. That way, anything short of a disastrous debate performance can be claimed as a knockout victory.

A big embarrassment came this week for the Republican Party, which has made voting integrity and fighting voter fraud a major issue.

A consulting firm hired by the Republican National Committee to register voters in five battleground states has been let go after one of its workers apparently submitted over 100 questionable registration forms in Florida's Palm Beach County.

The party severed its ties with the firm — Strategic Allied Consulting — because it has "zero tolerance" for voter fraud, said RNC spokesman Sean Spicer.
