It's been something that's been dogging me for the past 2 years. Despite the fact that I've successfully found and archived results for elections, I have yet to find much presidential data for the 1964 presidential election by the year's respective districts. I've only gotten bits and pieces so far; election data for my home state of Washington, plus some districts in other states that didn't split county lines.
I admit, I may have already sent a couple of PMs to people who may have the data. However, due to the fact that said people haven't been posting as much lately, plus me being OCD, I thought it may be worthwhile to bring this to the community. If you do have said data, you may send it to me via personal message on this site.
Thank you, and have a wonderful day! <3
