The bill passed the House Ethics & Elections Committee 11-7 Monday.
With the date change for the primary election would come a host of other changes.
Under the proposal, petitions from candidates would begin on Jan. 13 and be filed with the State Board of Elections between March 7 and 14, residents would be able to seek vote-by-mail ballots beginning March 30 and no later than June 23, and in-person early voting would begin May 19 - among other changes.
The measure comes as lawmakers await the release of "block-level" population and demographic data from the 2020 Census, which is not scheduled to be released until mid-August at the earliest.
