  We propose the maximin support method, a novel extension of the D'Hondt
apportionment method to approval-based multiwinner elections. The maximin
support method is based on maximizing the support of the least supported
elected candidate. It can be computed efficiently and satisfies (adjusted
versions of) the main properties of the original D'Hondt method: house
monotonicity, population monotonicity, and proportional representation. We also
establish a close relationship between the maximin support method and
Phragm\'{e}n's voting rules.
