Senate Republicans are scrapping a vote on the proposed Graham-Cassidy bill. This was the third attempt to "repeal and replace" the Affordable Care Act, or Obamacare.

The bill's authors - Senators Lindsey Graham, (R-S.C.), Bill Cassidy, (R-La.), Dean Heller (R-Nev.), and Ron Johnson, (R-Wis.) - explained the failure as resulting in "circumstances under our control and not under our control, the process and timing of this vote did not line up this time" and assured their constituents, "we will push on."

Republicans criticized Obamacare from its inception saying Americans shouldn't be required to have or purchase health insurance, that it cost too much, did little to control healthcare costs while premiums increased and choices of insurance were limited.

At the same time, millions of uninsured Americans -- many with pre-existing conditions -- now have health insurance and billions of dollars from the federal government have helped states expand Medicaid for those who couldn't afford insurance.

On Thursday's Smart Talk, we discuss the future of health insurance with Pennsylvania's Acting Secretary of Human Services Teresa Miller. Secretary Miller testifed this week against the Graham-Cassidy bill.

Also, Bill James is considered the godfather of baseball sabermetrics - a method of using empirical data to gauge a baseball player's productivity.

James used those analytic skills in a different arena when he investigated the crimes of a hundred-year-old serial killer, who terrorized small towns throughout the country. The investigation uncovered dozens of murders that were thought to be unconnected and sometimes led to the conviction, execution and even lynching of innocent people falsely accused.

With his daughter, Rachel McCarthy James, Bill James compiled his findings and even name the man they think committed the murders in The Man from the Train: The Solving of a Century-Old Serial Killer Mystery. Smart Talk speaks with the father/daughter team about the book Thursday.
