> That's a radical shift from the 6% of Americans who thought so according to a Gallup survey

The Gallup poll was filing people into three categories on that question (yes/no/uncertain). The YouGov survey filed them into four categories (definitely yes/probably yes/probably no/definitely no). If we assume that the two "probably" categories in the latter correspond to the "uncertain" category in the former, the results of the two surveys are fairly close.
