Seattle on Wednesday issued proposed rules governing which app-based taxi drivers could vote to unionize, drawing rebukes from both Uber Technologies Inc. and Lyft Inc.
 The draft rules, released by the Seattle Finance and Administrative Services department, allow for drivers with at least 52 rides over a three-month period to vote in a potential union election.
 That qualification excludes more infrequent drivers, which Uber and Lyft say would lead to a less-representative vote. Full-time drivers are more likely to support the idea of unions than part-time drivers, who prefer the flexibility of contractor status.
