Little surprise here: Philadelphia registered voters are still overwhelmingly Democrats. In fact, the city's voting demographics haven't changed much at all in the last four mayoral primaries.
Voter registration numbers for the 2015 primary, released Monday, show Democrats outnumber Republicans 7 to 1.
In the past decade, Democratic registration has basically stayed the same, with Republican registration dipping from 17 percent of registered voters in 2003 to 11 percent this year.
The deadline to register for the May 19 primary was April 20.
While the city's population may be growing, there are 41,000 fewer registered voters for this primary than there were in 2014, though only 4,800 fewer than there were in 2007 - the last time the city had a contested Democratic mayoral primary.
Here's a fuller breakdown:
Of the 2015 registered voters, 776,750 are registered Democrats (78.6 percent), 110,944 are Republican (11.2 percent), 6,717 are Independent (.7 percent) and 93,327 are registered with another party (9.5 percent).
In the 2011 primary, the city's registered voters were 78.5 percent Democrat, 12.5 percent Republican and 8.9 percent other.
In the 2007 primary, registered voters were 75.6 percent Democrat, 15.1 percent Republican and 9.2 percent other.
And in 2003 primary, voters were 75.7 percent Democrat, 17.8 percent Republican and 6.5 percent other.
