On February 16, filing for the Pennsylvania presidential primaries closed. All candidates need petitions to get on the ballot. A presidential candidate needs 2,000 signatures on his or her own petition, and additional petitions for delegates.

The Pennsylvania Elections Department has this list of presidential candidates who filed petitions. Republicans who filed are Jeb Bush, Ben Carson, Ted Cruz, John Kasich, Marco Rubio, and Donald Trump. Democrats are Hillary Clinton, Rocky De La Fuente, Bernie Sanders, and Willie Wilson.

An earlier version of this post said that John Kasich did not file a petition, but that was based on an incomplete list from the Pennsylvania Elections Department. Kasich was added to the list at about 6:30 p.m. eastern time.

On February 16, the voter rights organizations who had sued North Carolina over its U.S. House district boundaries filed this reply brief in the U.S. Supreme Court. The briefs on whether the lower court ruling should be stayed are now all complete, and the U.S. Supreme Court should rule very soon on whether the 2016 election should use the old districts, or districts that have yet to be drawn. If the stay is denied, there will almost certainly need to be a second primary in North Carolina this year, one for U.S. House, held after the new districts are in place. Thanks to Rick Hasen for the link.

According to this story, tens of thousands of Florida voters have recently switched from being independents, to being registered Republicans or Democrats, so that they can vote in the March presidential primaries. February 16 is the deadline for registration for those primaries.
