Republicans trail Democrats in Arizona, Tennessee Senate races

Two new CNN polls released Monday show Democratic candidates leading Republicans in Senate races in Arizona and Tennessee — two crucial states that Democrats hope to flip in November.

By the numbers: In Arizona, Democratic Rep. Kyrsten Sinema is leading Rep. Martha McSally by seven percentage points, 50% to 43%. And in Tennessee, former Gov. Phil Bredesen has a five-point edge on Rep. Marsha Blackburn— 50% to 45%.
