In 2018, 22 U.S. states were Democratic in party orientation, based on the party preferences or leanings of their residents. Another 18 were Republican and 10 were competitive. That four-state Democratic advantage is typical of what Gallup has found in recent years, though Democrats enjoyed much larger leads in 2008 and 2009, and Republican states outnumbered Democratic ones in 2015 and 2016.
