Turnout appears at first glance to be stronger this year in Philadelphia for the closely watched midterm primaries than it was in the off-year election last November, according to a blog that analyzes voter data.

The latest news on the 2020 presidential election
This year is a midterm year, and two major races are on ballots: open races for Pennsylvania governor and a seat representing the state in the U.S. Senate.
Outgoing Gov. Tom Wolf is not allowed to run for a third term and U.S. Sen. Pat Toomey is resigning.
Turnout will definitely pale in comparison to the presidential election in 2020. Philadelphia voters cast more ballots in that election than in any election since 1984, according to official results.
The city overwhelmingly voted for President Joe Biden, by a margin of 81% to 19%, compared to former President Donald Trump.
The strong turnout is credited with helping Biden win Pennsylvania, which in turn secured the presidency for the Democrat.
