Pa.'s 2023 municipal elections are behind us. A peek at what's at stake in critical 2024.

An election for municipalities, counties, school boards and the commonwealth's top court concluded this week in Pennsylvania.

Even as those results roll in, many eyes are already focused on pivotal 2024 races. Here's how Pennsylvanians will begin to shape the political world at the state and federal levels in just a few months.

When is the next presidential election?

President Joe Biden is up for a second term in 2024.

Though White House incumbents rarely face significant challenges from within their own party during the primary, the general election is different. The race in November could well be a 2020 redux because polling has shown that former President Donald Trump — despite multiple federal indictments — remains a heavy favorite among likely Republican voters in a GOP field that includes Florida Gov. Ron DeSantis, Nikki Haley and several others.

A recent USA TODAY/Suffolk University Poll shows Biden and Trump tied nationally at 37%, with independents Robert F. Kennedy Jr. and Cornel West garnering 13% and 4%, respectively.

The general election is set for Nov. 5, 2024. Pennsylvanians who want to register to vote or change their party affiliation in time for this must do so at least 15 days before the election, which is Oct. 21 in this case.

When is the Pa. primary election in 2024?

Most political hopefuls who want to secure a place on the November ballot will first have to survive their party's primary race. Pennsylvania, after some bipartisan debate among lawmakers, is sticking to its original date of April 23.

While members broadly agreed that an earlier primary would be preferable, the Pennsylvania Legislature failed to find consensus around a new option.

The Republican-led Senate advanced a proposal for March 19, with Democratic leadership in the House seeking a change to April 2. Both sides said they wanted to avoid the current conflict with the Jewish Passover holiday and to give Pennsylvanians more influence through an earlier vote.

Who is up for re-election in Pa. in 2024?

In addition to the presidential race, Pennsylvanians will weigh in on the compositions of U.S. Congress and the state General Assembly.

Near the top of the ticket will be U.S. Sen. Bob Casey, a Democrat who is seeking a fourth term in the office. David McCormick, following his 2022 GOP primary loss to Dr. Mehmet Oz for a vacant U.S. Senate seat, is mounting a challenge to Casey in the general election and has already scored the support of some major Republican donors.

The nine Democrats and eight Republicans of Pennsylvania's congressional delegation will be tested as well.

Democratic U.S. Reps. Susan Wild, Matt Cartwright and Chris Deluzio are among the GOP's top targets in the commonwealth, according to the National Republican Congressional Campaign. The Democratic Congressional Campaign Committee, meanwhile, sees Republican U.S. Reps. Brian Fitzpatrick and Scott Perry as vulnerable.

The state-level races will reverberate loudly at the Capitol in Harrisburg.

Every member of the Pennsylvania House of Representatives will need to win re-election next year to keep his or her seat. The Democrats hold a precarious one-vote lead in the House.

Seats for half of the state's 50 senators will also be on the ballot, putting the Republicans' 28-22 lead in question.

Other major races in Pennsylvania include contests for the offices of attorney general, auditor general and treasurer.
