No -- she's being practical. We are going to have a razor-thin margin in the House, and least one RINO has announced he's willing to work with Democrats to elect a speaker if Republicans can't agree. So if McCarthy has the support of the majority of Republicans in the House, but the Freedom Caucus won't vote for him for Speaker, we get a Democrat speaker.
That would be the worst possible outcome, so MTG is just doing what makes the most sense.
Think about it harder.
