The Supreme court ruled Monday that a state can draw legislative districts based on total population, bringing back into light the case of one person, one vote from the 1960s. Until Monday, that doctrine wasn’t specified to be applied to the general population or the voting population.
Looking at this ruling from the perspective of both major political views, if the court ruled that districts be drawn by voting population, then more voting power would be shifted to rural areas, which are widely conservative, in contrast to urban centers with higher populations which tend to vote liberally. In the end, the unanimous ruling by the Supreme Court seems to benefit the Democrats.
The case was brought forward by two Texas voters who felt their vote was being diluted by voters in other districts and urged district lines to be drawn by eligible voters.
