In the real world, demographic change is gradual: Every day, the country becomes a tad more diverse as babies are born, people immigrate, and others die.

But in elections, demographic change happens fast: in a surge of new voter registrations ahead of a presidential election. Just who registers and how many will be one of the biggest stories of the next month.

This wave has probably just begun, even if it isn’t yet reflected in the available voter registration data. For now, we’re left to read tea leaves — and they look good for Democrats.

Google trends data indicates that the searches for voter registration have surged over the last week — and that the highest rates of searches have been in disproportionately Hispanic areas.
