Like their GOP counterparts, Chester County Democrats will have four names to choose from when they select two candidates for county commissioner in the May 15 primary.

The party convention Tuesday night ended with no one getting the 148 ballots needed for an endorsement.

The top vote-getter, at 136, was Virginia McMichael, a lawyer and East Whiteland Township supervisor. She was followed by Bill Scott, a lawyer and former West Chester councilman, at 135; Kathi Cozzone, an accountant and financial analyst from Uwchlan Township, at 124; and Ken Knickerbocker, a software company executive and president of the Parkesburg Borough Council, at 120.

"So we're agreed that we have four terrific candidates," said Michele Vaughn, chairwoman of the Chester County Democratic Committee.

Last week, the Republicans endorsed Recorder of Deeds Terence Farrell and Commissioner Carol Aichele, the latter by a slim margin. But former Republican jury commissioner Sandy Moser and county Treasurer Alan J. Randzin also plan to be on the ballot.

With a 2-1 voter-registration edge, Republicans have historically been guaranteed two commissioner seats, with the third seat going to the minority party.

But that registration margin has shrunk, and a theme of "opportunity" echoed throughout the Democrats' convention.

The Democrats gave "unanimous endorsements" to three candidates seeking county row offices and a county judicial candidate: Kipp Stone, a former bank executive from West Goshen, for register of wills; Downingtown lawyer John H. Kiefel for prothonotary; East Bradford Township auditor Kevin Fitzpatrick for recorder of deeds; and lawyer and educator Jennifer Levy-Tatum of West Bradford for a new seat on the Chester County bench.
