The WI legislature is not in session, Walker will have to call a special session to certify. Watch the democrat legislators boycott the session causing a lack of quorum. They’ve done it before.
Of course the outrage and backlash against them will be terrible, but I really think they don’t care.
Are they going to flee the state again? Going to try to recall Walker over this? We have seen how that goes once before.
I am also pretty sure that if Wisconsin is out of the mix than Trump doesn’t need 270 he needs 270 less 1/2 of Wisconsins number of electors.
