Big surge in PA voter registrations

Going by the Pennsylvania statewide voter file updated last night, the last week since VP Harris become the presumptive Democratic nominee has seen a dramatic increase in registrations compared to the previous week, the lion’s share of increase coming from female voters:
 

	reg	Female	male	D	R
WEEK FOLLOWING BIDEN ANNOUNCEMENT	17,585	7,493	5,549	7,150	6,041
PRIOR WEEK	12,391	4,004	4,123	3,099	5,949

*note:  not all voters have gender specified in the voter file

Hear the roar. So there was a 41% increase week-to-week in total registrations, about 57% of which were female compared to 49% female in the previous week. Registered Democrats were 54% of the new registrations compared to only 34% the prior week amid the Democratic doldrums. There was an 87% increase in female registrants and a 35% increase in male registrants week-to-week.

The chart above shows the percent increase week-to-week in registrations by voter age. The largest increases were generally among younger voters, although there were substantial increases across the board. Registrations of voters under age 35 were 71% of the total.
