Supporters of the president, some of them armed, gathered outside the home of the Michigan secretary of state Saturday night. Racist death threats filled the voice mail of Cynthia A. Johnson, a Michigan state representative. Georgia election officials, mostly Republicans, say they have received threats of violence. The Republican Party of Arizona, on Twitter, twice called for supporters to be willing to “die for something” or “give my life for this fight.”

“People on Twitter have posted photographs of my house,” said Ann Jacobs, the chair of the Wisconsin Elections Commission, who alerted her neighbors and the police about the constant threats. She said another message mentioned her children and said, “I’ve heard you’ll have quite a crowd of patriots showing up at your door.”…

“They’re getting more angry, and we’ve been getting emails all the time, all hours of the day and night,” said Jennifer O’Mara, a Democratic state representative in Pennsylvania. She said her staff had been subjected to threats, as had her Republican colleagues. “A lot of calls are saying we won’t be forgetting.”
