Melissa Alexander came to the Tennessee statehouse to convince members of the Republican party – her party – to adopt gun control measures after a mass shooting at her son's school. A year later, she doesn't feel like she's gotten through to many lawmakers. But there's at least one Republican senator who's made Melissa and the other Covenant moms feel welcome: Richard Briggs. Briggs has been in office for about a decade. He's a doctor and an army veteran. And recently, he's had to navigate a statehouse in transition. Briggs represents a faction of the Republican majority that isn't often visible: those who are concerned about the GOP's shift further to the right. They feel that they are a minority within the majority – stewards of what the party used to be. As Melissa contemplates a big decision, we turn to Briggs' story. What can more moderate Republicans achieve in the Tennessee legislature? And will Melissa decide to follow the path that Briggs has already been down?
