House Speaker Mike Johnson of Louisiana became speaker a little more than a year ago after eight Republicans joined with Democrats in booting Kevin McCarthy from the job.

The social conservative inherited many of the same troubles that plagued his predecessor when it comes to unifying the conference. He has had to rely on Democratic votes to keep the federal government open and needed their help to prevent the kind of mutiny that toppled McCarthy.

Johnson tied his political fortunes to Trump, showing up at the latter’s hush-money trial in New York and embracing his claims of political persecution.

Johnson will be favored to remain as speaker if House Republicans maintain their majority, but could face a serious challenge as the Republican leader should the Democrats take control of the chamber.
