Pick two or more counties and compare them across every variable at once — elections, population, CVAP and population composition. The widest spread in each row is highlighted. County-level today; comparing a place to its own past (and other geography levels) arrives as historical vintages land. A comparison of places, not a claim about individuals.
Add counties above to build a comparison. Try Harris (TX), Los Angeles (CA), Maricopa (AZ).
