Please explain, "the law of the land?" what' s the meaning of it?
All that seems impressive, but here’s the rub: many Americans do not believe Mrs Sebelius. Roughly half of those polled by KFF thought Obamacare had already been repealed or were unsure of its legal footing. It remains the law of the land.
I don't understand the last sentence's meaning. Is it the law about land? It doesn't make sense here.
