This Is Our Land — Brad Smith

When a deranged loner kills twenty-six people in a Pennsylvania schoolyard, the country is stunned and devastated. Among those catatonic with grief is Jo Matheson, an organic farmer who has lost her goddaughter in the shooting. Sam Jackson, an egotistical right-wing TV talking head, has sliding ratings and faces imminent cancellation. He arrives in Pennsylvania and during a rant, he blames the parents of the dead children. He intends the tirade to be his last salvo but, incredibly, his ratings climb, while Jo watches from her farmhouse in upstate New York, incensed. Sam rides the wave, shouting that it's time to take the country back from the left-wing weaklings who don't have the courage to protect their children. When he is asked to run for Congress, he accepts and amplifies his message. Watching these developments in horror, Jo finally decides that there actually is something she can do.
She kidnaps Sam's ten-year-old daughter.
