In a move regarded with equal amounts fanfare and vitriol, the US supreme court ruled Thursday 5-4 to uphold the Obama administration's Affordable Care Act.
In the span of 24 hours, chief justice John Roberts has come to be regarded as either a liberal hero or a conservative outcast; the law a revolutionary answer to an unsolvable problem or harbinger of American doom; and the 2012 election itself won or lost.
Whatever it is you read or believe, there's plenty of material to prove your point either way.
Writers Ana Marie Cox, Harry Enten and Jason Farago will join our weekly US politics live chat to answer any questions you may have about the consequences for politicians and voters alike.
