Writer Nicholas Confessore's object examples are three states: "Alabama’s transformation was the product, in part, of a sophisticated political apparatus designed to channel political money from around the country into states where conditions were ripe for Republican takeover. In 2010, the effort achieved striking success, moving a dozen states to sole Republican control, including presidential swing states like Ohio and Pennsylvania. In 2012, a resurgent Democratic version — financed chiefly by labor unions and wealthy liberal donors rather than corporations — began to catch up, spearheading Democratic takeovers in Minnesota and Colorado. Their combined work has helped remake the nation’s political landscape. Republicans or Democrats control both the legislature and the governor’s office in 36 states, the most in 60 years."

Confessore's article explains in detail how that works. Read the story.
