In West Amwell, where a judge has ordered a do-over of the 2019 township committee race, 29% of voters have already returned their ballots for the May 12 all-VBM special election between Republican Lucas Lyons and Democrat Lawrence Herman.
Registered Republicans are returning vote-by-mail ballots at a greater pace than Democrats, while unaffiliated turnout is low.
Of the 675 ballots returned so far, 313 (38%) have come from Republicans, 214 (32%) from Democrats, and 150 (17%) from unaffiliateds.
Ballots must be mailed by 8 PM Tuesday to be counted, although election officials will accept ballots postmarked by the deadline until close of business on Thursday.
Republicans have make up 35% of the West Amwell electorate, while Democrats account for 28%.
Lyons had defeated Herman last year by a vote of 535 to 391, 58%-42%, but his win was invalidated after the courts found Lyons did not meet the 12-month residency requirement.
The special election had been set for March 31, but was moved to next week as part of an executive order by Gov. Phil Murphy consolidating March, April and May elections to an all-VBM contest to help stop the spread of COVID-19.
