Yesterday afternoon, Montgomery County's voter rolls lost 79 Republican registrants and gained 48 Democratic ones, further narrowing the registration gap there to about 21,600, less than 5 percent of the county's total.
That gap had been 30,000 in November and was more than 23,000 on Friday.
"Even before we realized that we're the game in many ways, it was clear that there was a tremendous amount of enthusiasm," Montgomery County Democratic chair Marcel Groen said.
In solidly Republican Chester County, Democrats are also making inroads. Since November, Democrats have registered more than 5,600 new voters, Republicans just 1,369.
In Montgomery County, interest in the primary has provoked some concern about the abilities of the machines that will count the ballots.
Montgomery is one of only two Pennsylvania counties using the Sequoia AVC Advantage voting machine, now the subject of an inquiry by the New Jersey Attorney General's Office over problems that arose in that state's February primary.
