Speaker saga takeaways: Why Mike Johnson won and his coming challenges

The stunning rise of newly minted Speaker Mike Johnson (R-La.) marks the end of weeks of chaos in the House and the Republican Conference. 

After bitter and personal battles sank three other Speaker options, House Republicans found Johnson to be the conservative constitutionalist with a dash of Southern charm that they needed to end the turmoil at the right time — giving him unanimous GOP support.

But even though the biggest intraparty crisis is over, the House and Republicans face immediate challenges over government spending, as well as wartime aid to Israel and Ukraine.
