American public opinion can sometimes seem stubborn. Voters haven’t really changed their views on abortion in 50 years. Donald J. Trump’s approval rating among registered voters has fallen within a five-point range for just about every day of his presidency.
But the Black Lives Matter movement has been an exception from the start. Just look at the graph below. The graph shows the ''support'' which is a measure showing the percent of respondents who supported a policy minus the percent who said they did not support it.·Over the last two weeks, support for Black Lives Matter increased by nearly as much as it had over the previous two years, according to data from Civiqs (the data originates from the Civiqs daily tracking poll of registered voters).
Will the recent shift in opinion last? News events can sometimes cause a shift in public opinion that quickly dissipates. After mass shootings, for instance, big spikes in support for gun control typically ebb as soon as memories of the bloodshed fade. But there are reasons to think that the Black Lives Matter movement might be different.
There’s no way to know what will happen next. After all, no one just a few years ago would have predicted that a majority of Americans would say they have a favorable view of Black Lives Matter.
