I fully agree that the landscape could change once Mueller’s report has been released, and the article you’ve linked seems to imply that, too:
"Now. Pelosi’s arguments about impeachment deal with the here and now. Wary of handing Trump and Republicans an issue to campaign on, she has sought to downplay the idea in the context of the midterms. "
" Pelosi’s stance on not talking about impeachment right now, her allies would argue, doesn’t preclude her from embracing such a move post-election if circumstances change. In fact, Pelosi has nodded to the ongoing special counsel probe by Robert Mueller as something that needs to play out before the party even seriously engages with the idea of impeachment."
