Nebraska state Senator Mike McDonnell has blocked a Republican-led push to change the state’s method of allocating electoral votes from a district-based system to winner-take-all. McDonnell, a former Democrat who switched parties in April, represents an Omaha-area district that is key in presidential races. The effort was backed by former President Donald Trump and aimed at securing all of Nebraska’s electoral votes for the Republican nominee. McDonnell announced he would not support the change so close to the election, effectively halting any chance of a special legislative session to move the bill forward.
