Republican Kevin McCarthy rode the tiger of far-right US politics led by Donald Trump to achieve his dream of becoming House speaker early this year. Then on Tuesday, the tiger turned and ate him. The 55th speaker of the House of Representatives was booted out in a shock vote brought by rebels in his own party who have seethed in the nine months since McCarthy narrowly quelled their attempts to block him and managed to claim the most powerful

job in Congress.

No other speaker — a position second in line from the presidency in the federal

hierarchy — has been ousted in US history. There is no obvious successor to oversee the House Republican majority. No matter which Republican replaces McCarthy, the divisions within the party will remain. And the challenges to effectively running the chamber are still the same.
