It's close enough to "most" that I think it's worth rounding up in most conversational contexts.

This isn't some minority view committing a coup. This is a pretty-damn-near majority using the electoral process to give itself a thumb on the scale to win.

It may not be "what America really is", but it's also not not who America really is. It's fair to say that this is who the world should continue to expect us to be, and that we'll continue to think that this is a democratic country. (Not just that 49.8%, but a large majority, even most of those who oppose the present government.)
