If people move away from a region that is typically Democratic, such as the Northeast, to a region that is typically Republican, such as the South, it will affect how many electoral votes each state has. Because most states use a winner-take-all system to allocate Electoral College votes, this may mean that Republicans will be able to rely on more electoral votes as a baseline of support. Over a longer time frame, if enough Democratic-leaning voters move from the Northeast to the South, it could turn some of the safe Republican states in the South to swing states that Democratic candidates could win.
