Arizona is a battleground state in national elections and could sway the outcome of the 2020 presidential race.  
But how did we get here? How did the state go from reliably red to purple, with the possibility to shift blue in 2020, in just a decade? To understand, go back to 2010 when Arizona surprised the nation by passing Senate Bill 1070, a sweeping and highly controversial immigration law, otherwise known as the "show me your papers" law. 
That's what Valley 101's sister podcast will explore in season two of Rediscovering. The five-part series will examine what led to the bill, what its proponents sought to do, how the community and nation reacted, and how its effects linger still today. 
This week on Valley 101, host Kaila White will speak to the hosts of Rediscovering: SB 1070, The Arizona Republic's national political reporters Yvonne Wingett Sanchez and Ronald J. Hansen. They also host our political podcast, The Gaggle. They'll take you behind the scenes for a sneak peak of what to expect in the new series.
