Alabama write-ins for U.S. Senate will all be counted and canvassed, according to this story. This will be the first time Alabama has ever included write-in totals for any statewide office in its official canvass. Although Alabama has always permitted write-ins, and counties were supposed to count them, historically they have not been counted. And even in recent years when most counties did canvass write-ins, the Secretary of State would never release a statewide total for any write-in candidate. Without an official state tally, the publications that publish election returns would always refuse to include Alabama write-ins.
Even when Harry Truman was off the Alabama November 1948 ballot, and even when Lyndon Johnson was off the November 1964 ballot, Alabama election officials did not release any write-in totals for either candidate, or for any Democratic candidates for presidential elector. Alabama is the only state in the last 100 years which reported zero votes for either a Democratic or a Republican presidential nominee in a general election. Thanks to Rick Hasen for the link.
