From a front-page New York Times news article about the effort to repair the ObamaCare Web site: "The scrambling underscores the pressures on the administration to fix what is widely viewed as the president's biggest domestic achievement."
It's not clear from the sentence or the article what the "what" is. ObamaCare? The ObamaCare web site? Both things may be "widely viewed" within the Times newsroom as big achievements, but elsewhere, skepticism reigns.
