According to data from AdImpact, Republican candidates nationwide have recently increased their spending on ads attacking Democrats' approaches to crime and public safety.

We're joined by Rena Karefa-Johnson, Director of National programming at FWD.us, and Ames Grawert, Senior Counsel at the Justice Program at the Brennan Center for Justice at NYU.
