Gerrymandering relies heavily on a winner-take-all approach. In other words, the less the system is proportional, the bigger the risk of gerrymandering. Namely, when 51% of voters earn 100% of representation, this electoral engineering can easily make some votes count to their full potential and annul the effect of other votes. Moreover, gerrymandering has become easier today due to the application of new technologies which may help draw districts more precisely to respond to partisan preferences.
