Former two-term Minnesota Gov. Tim Pawlenty's campaign for the GOP presidential nomination was always expected to be launched, or extinguished, in next-door Iowa.
But with his once-promising prospects seemingly atrophied, and his first big test at the Iowa GOP presidential straw poll less than a month away, Pawlenty has embarked on an 18-city tour of the state this week to pump up his stuck-in-single-digit support.
He's also plowing about $200,000 into television advertising that will run through the Aug. 13 straw poll — the heftiest candidate buy in Iowa so far.
This week's meeting of the International AIDS Society Conference comes with a CDC study showing a major advance in sexual health. Correspondingly, Botswana trials showed the drug Truvada prevented HIV transmissions in more than 60 percent of heterosexuals. The study's author Dr. Michael Thigpen and host Michel Martin discuss how much Truvada costs, why HIV is so pervasive among women in Botswana, and how much people must take the drug for it to be effective.
