Republicans can consistently win according to the rules but without getting a majority of votes nationwide due to advantages in the Senate, Electoral College, and redistricting. Gerrymandering is the drawing of district lines to guarantee a desired electoral outcome, which can provide an advantage for candidates from a certain party.
