On this week's episode of 'The Sunday Show with Jonathan Capehart': Dead Heat. Kamala Harris and Donald Trump ramp up their messaging on the campaign trail as the new NBC News poll shows them tied. Senior political editor Mark Murray will break down the numbers and I'll ask him the implications of the yawning gender gap they show. Lone Star battle. Rep. Colin Allred is hoping he'll be the one to oust Republican Sen. Ted Cruz from the Senate. Can he actually pull this off? I'll ask him! Under scrutiny. Charles Coleman Jr. and Maria Teresa Kumar join me to discuss the intense spotlight on Black and Latino voters and whether they actually wield the power the New York Times/Siena poll implies they have. I'll also take a deep dive into the life of late Civil Rights icon, Rep. John Lewis with the author of a new biography that showcases Lewis's remarkable transformation from student activist to a national moral force in Congress. All that and more on "The Sunday Show with Jonathan Capehart."
