The endorsement from Take Action Minnesota is very thoughtful and well written. The DFL page on Ellison's GOP opponent, Doug Wardlow, is frighteningly illuminating:
A DISASTER ON CIVIL RIGHTS
After Eagan residents rejected Doug’s anti-family views and voted him out of office, Doug found a new home for his far-right legal activism at the Alliance Defending Freedom (ADF), an anti-LGBTQ hate group. Doug proudly supports the organization’s work to recriminalize homosexuality, oppose hate crime laws, and sterilize transgender individuals. Wardlow himself has gone so far as to say that the Supreme Court recognizing marriage equality was a “totalitarian impulse… not many steps from tyranny.”
Wardlow is extremely hostile to voting rights and has openly claimed he will use his power as Attorney General to help Republicans win elections. In 2012, he claimed “you're not born with the innate right to vote” while defending the restrictive Voter ID constitutional amendment Minnesota voters rejected soundly in 2012. In 2017, Wardlow claimed that, if elected as Attorney General, he would “change the political complexion of the state long term" to favor Minnesota Republicans by aggressively prosecuting "illegal voting." In August of 2018, Wardlow doubled-down on and claimed that, as Attorney General, he’ll use the office to help make a "Minnesota that’s more red."
