Weeks of threats to oust Johnson over Ukraine aid fizzled Saturday when Rep. Marjorie Taylor Greene left town without pulling the trigger.

Why it matters: Greene is still talking the talk, but momentum for an ouster effort against Speaker Mike Johnson that seemed certain now has no timeline and no new endorsers.

• Greene said she will "go home and hear from their constituents" before making her decision following weeks of threats to force a vote to oust him.
• "He needs to do the right thing and resign ... If he doesn't do so, he will be vacated," Greene said Sunday on Fox News.
• "When John Boehner was replaced, it wasn't by a motion to vacate on the floor" but rather his pre-announced resignation, said Rep. Thomas Massie, who joined Greene on the motion to vacate.

Zoom in: "I think it strengthens him — he showed strength," Rep. Brian Fitzpatrick (R-Pa.) told Axios about Johnson bringing the motion to the floor despite his party's opposition.

• "He's a real Reagan Republican. It reminds me of Reagan's handling of Gorbachev," said Rep. Mario Diaz-Balart (R-Fla.).

The big picture: As his party's fourth choice for a speaker — after Kevin McCarthy, Steve Scalise and Jim Jordan — Johnson has repeatedly gone bipartisan.

• March 6: Johnson bypassed a conservative blockade to pass six spending bills with a bipartisan majority.
• March 22: Johnson passed $1.2 trillion in spending with less than half of the GOP on board.
• April 20: Johnson muscled through $60+ billion in Ukraine aid despite a majority of Republicans trying to block it on three different votes.

Between the lines: Opposition from conservatives has weakened Johnson's hand in negotiations, moderate House Republicans told Axios.

• "Truthfully they might prefer losing," one House Republican said of conservative hardliners.
• "[We] could have gotten the Democrats to fold on a variety of border policy changes. ... But in the end, we lost our leverage because we weren't negotiating as a majority," another House Republican told Axios.

What's next: House insiders expect Johnson to largely run out the clock until November, with lots of extra recess time.
