Always remember that policy universally is promoted to further the agenda of a given party! Many republican politicians opt for the abolition of early/absentee voting, and democrats the opposite. Bear in mind that these policies are not just ideological rhetoric, but political play, intended to benefit the ruling party rather than the wider people.
I highly doubt Trump wins every single state. What’s the source for your info?
The map is nonsense. Democrats take advantage of early voting for so many reasons, Republicans prefer in-person election day voting for their own reasons.
There are many more Democrats than Republicans, they just don't vote as much. The map.could easily be labeled: what would happen if every barrier to voting was removed vs what would happen if Republicans were allowed to implement all of the voter suppression tactics they can imagine.
Unfortunately I am not the original creator of this map, however election results and demographics are provided by every state’s Secretary of State and/or elections office, and is accessible via each state’s respective website. For example, this is the website for Ohio.
