Candidates in competitive House and Senate races across the United States spent Labor Day weekend engaging with voters at festivals, union halls, and parades as the midterm elections enter their final stretch.

In Maine, Troy Jackson, the Democratic nominee for U.S. Senate, addressed union members, pledging to advocate for a higher minimum wage and expanded family medical leave if elected. Jackson, a former labor activist, is challenging Republican Sen. Susan Collins in a race seen as crucial for Democratic hopes of controlling the Senate.

Meanwhile, Sen. Collins visited Bath Iron Works on Sept. 1, highlighting her commitment to securing contracts and wage enhancements for shipbuilders.

President Donald Trump is also intensifying his efforts for Republican candidates. His party is scheduled to hold a two-day convention in Dallas this week, an event designed to generate enthusiasm for the GOP ahead of the November general election. Historically, the party holding the White House tends to lose seats in Congress during midterm elections. Trump has announced plans to campaign in numerous House and Senate battlegrounds in the 30 days leading up to the election.

In Georgia, Democratic Sen. Jon Ossoff and gubernatorial candidate Keisha Lance Bottoms attended an AFL-CIO picnic. Ossoff criticized the economic circumstances of working families, attributing their struggles to inflation and what he termed corruption under the current administration. He is running against Republican Rep. Mike Collins. Bottoms, facing healthcare CEO Rick Jackson, urged union members to leverage their networks to counter her opponent's campaign spending, noting Georgia's historically anti-union environment and "right to work" laws.

In Wisconsin, a closely contested House district saw Republican Rep. Derrick Van Orden and Democratic candidate Rebecca Cooke participating in a local parade. Voters expressed a range of concerns, from frustration with both parties to a desire for economic relief, such as lower food and gas prices.

In Ohio, a violent incident occurred at a fair on Sunday when an armed assailant charged toward Democratic gubernatorial candidate Amy Acton, injuring several people. A spokesperson for her opponent, Republican Vivek Ramaswamy, stated that candidates should be able to campaign without fearing threats or violence.

With the first statewide mail ballots already sent out in North Carolina, campaigns are expected to become increasingly intense and costly as the November 3 general election approaches.
