In last week’s poll, conducted before the Court heard arguments over a new Mississippi abortion law, far more Americans said either that it was unlikely that Roe would be overturned or it definitely won’t happen (36%) than said it definitely will happen or was very likely (15%). This week equal numbers think it more likely than not as think it more unlikely than not that Roe is overturned. In both weeks about half of Americans said there was a 50% chance.

Last week, there was not a big difference in expectations about the Court overturning Roe between Americans who want to see it overturned and those who don’t. Now, after the arguments on the Mississippi law, Americans who want Roe to remain are 10 points more likely than those who don’t to think its demise is likely or definite. Like last week, majorities of both supporters and opponents of Roe think the chance of it being overturned is at least 50%.
