House Speaker Mike Johnson, R-La., is launching a six-week, 22-state campaign blitz as Republicans make their final push to defend control of the House in the November midterm elections.

Johnson plans to visit more than 40 congressional districts through Election Day, splitting his time between vulnerable Republican-held seats and Democratic districts the GOP hopes to flip.

The nationwide campaign swing comes as Republicans face a tightening House battlefield. The Cook Political Report moved 15 House races toward Democrats on Sept. 25, with its latest analysis saying Democrats are favored in more districts than Republicans and that Democrats' most likely outcome is a gain of five to 15 seats.

Republicans currently hold a narrow majority in the House, meaning relatively few competitive races could determine control of the chamber next year.

Johnson's latest campaign tour begins this week with stops in Louisiana and New York before taking him across the country. His schedule includes Arizona, California, Colorado, Florida, Iowa, Maine, Michigan, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia, Washington and Wisconsin.

Johnson previously traveled to 18 states during an August campaign tour that included 75 events across 52 cities.

“With less than 40 days until the most consequential midterm election in modern history, Republicans are not slowing down as we give voters a clear choice between common sense and Democrats' crazy,” Johnson said.

“From coast to coast, I am leaving it all on the field to defend our House majority because the stakes have never been higher,” he added, accusing Democrats of embracing socialism and communism and nominating what he called some of the most radical candidates to run for Congress.

The speaker is also bringing significant financial resources into the final stretch of the campaign.

Johnson raised more money through the second quarter than any previous Republican House speaker or House leader during a midterm election cycle, according to campaign data cited by Axios.

Earlier this month, Johnson announced another $13 million transfer to Republican incumbents, challengers and the National Republican Congressional Committee as candidates entered the final weeks of campaigning.

The NRCC is also entering the closing stretch with a cash-on-hand advantage over the Democratic Congressional Campaign Committee. The Republican committee has about $13 million more cash on hand than its Democratic counterpart, according to Axios, giving the GOP additional resources for competitive House races.

The financial advantage comes as Republicans attempt to counter a political environment that has become more challenging in several battleground districts. Cook's latest ratings changes moved all 15 affected races in Democrats' direction, including several Republican-held seats.

Johnson's campaign schedule reflects the broad scope of the Republican effort. Rather than concentrating solely on defending vulnerable incumbents, the speaker is also traveling to Democratic-held districts where Republicans believe they have opportunities to expand their majority.

The six-week sprint will put Johnson on the ground in some of the country's most competitive congressional contests as Republicans seek to keep control of the House and prevent Democrats from gaining the small number of seats needed to take the chamber.
