"Her base remains steadfast, but her power outside of it seems to be shrinking as fast as the Republican majority in Washington," Murphy writes.
"Now Greene’s latest threat to oust Republican Speaker of the House Mike Johnson is giving even her fans anxiety over where it’s all going."

Murphy argues Greene stands at a crossroads as an ally of ousted House Speaker Kevin McCarthy who has kept the "plum" committee assignments he gave her but lost her hold on fellow Republicans.
"Although she remains close with Trump, she’s rarely mentioned as an option for vice president as she once was," Murphy notes.
There are also warning signs in Greene's district, Murphy argues.
While her crowd Tuesday cheered, Murphy contends that they were "not unanimous in who they were angry at, nor whether ousting Johnson without a replacement will solve any problems."
Republican and U.S. Army veteran Bob Roesch, who was asked to leave after he tried to ask Greene a question, said he had hoped to ask for more information about her anti-Johnson stance.
“You want to kick out Mike Johnson? Fine. I do, too, for several reasons,” he said. “But she can’t do it by herself, can she? I don’t think so. She needs other people, and I don’t know of one that’s going to side with her.”

Whitfield County Commission GOP candidate Christian Phillips, who supports Greene, told Murphy he holds the same reservations as Roesch.
“I understand Johnson is doing a lot wrong, but we have such a razor-thin margin that if we were to vacate, we could completely lose power,” he said. “I feel like we have to just be careful right now.”
Murphy issued a final warning for Greene about pursuing Johnson's ouster.
"Taking a swing at Johnson — and missing — could plunge the House GOP back into chaos and further isolate Greene on an island," she wrote, "where even her own supporters don’t agree with the risk she took to get there."
