Searches from California's most competitive swing districts are reflecting an outsize interest in health care issues, according to search data from Google Trends.
In nearly all of the seven districts rated "Lean" or "Toss Up" by the Cook Political Report, election searches around health care issues outnumbered interest in issues like immigration or the economy.
"We've seen health care become the biggest issue in search for a number of months," said Simon Rogers, data editor for Google's News Lab. "Really since the beginning of this year, it's certainly grown to dominate political searches."
The one exception was in the 25th District, north of Los Angeles. There, searches around minimum wage have outpaced health care searches so far this year, but in recent weeks, interest in health care has risen to the top of the Trends list.
The Trends data was custom-built for KQED by Google to focus on congressional districts. California's battleground House seats will help decide the balance of Congress in the November election.
