Tennessee's attempt to execute Christa Pike failed twice, leaving her alive in critical condition and pushing the governor to stop all executions this year — a turning point for the death penalty debate.

• Pike survived two doses of lethal injection and is now in critical condition, possibly with brain damage.
• It is believed to be the first time anyone has survived after being injected with lethal drugs, and Tennessee's second botched execution this year.
• Republican Governor Bill Lee called off executions for the rest of the year while still defending the death penalty itself.
• Marsha Blackburn, who wants Lee's job, suggested bringing back the electric chair; her Democratic opponent called for a full moratorium.
• Roughly 4% of people on death row are believed to be innocent, which with about 2,000 inmates means dozens of innocent people face execution.

Outlook: Tennessee faces an unresolved question of what to do with Pike, and the state's next governor's race will likely turn execution methods into a campaign issue.
