Sean Hannity said San Francisco is "spitting in the face" of law-abiding Americans by allowing non-citizens, including illegal immigrants, to register to vote in the November election for the city school board.

The move follows the city's passage of a 2016 ballot measure that gave the right to vote in school board elections to non-U.S. citizens over age 18 who live in San Francisco and have children under age 19, the San Francisco Chronicle reported.

"This is just one more sign that the left in this country, they don't care about rule of law, our Constitution, about the rights of the many. They don't believe in borders," Hannity said in his opening monologue Thursday.

He argued that this is an example of how Democrats are intent on regaining power at all costs.

He warned that if Democrats are able to make significant gains in this November's midterm elections, they will seek to implement a radical agenda, including opening the borders, rescinding tax reform, preserving ObamaCare, impeaching President Trump and blocking Trump's Supreme Court nominee.

"They're not proposing one thing that'll solve any problem for any American citizen," Hannity said. "It is without a doubt the most important midterm election of our lifetime. The future of this country is at stake. They want to undo the 2016 election."
