Gallup’s analysis of party affiliation in the U.S. states shows a marked decline in the number of solidly Democratic states from 2008 (30) to 2010 (14). The number of politically competitive states increased over the same period, from 10 to 18, with more limited growth in the number of leaning or solidly Republican states.
Even with Democratic Party affiliation declining during the past two years, Democratic states still outnumbered Republican states by 23 to 10 last year, and there were 14 solidly Democratic states compared with 5 solidly Republican states.
The United States, both nationally and in every state, has moved in a more Republican direction during the last two years. Though the losses are not welcome news for the Democratic Party, the decline since 2008 is from a high point in the party’s support, the highest in at least two decades. At the same time, the Democratic losses have not led to major gains in Republican affiliation. Rather, Gallup finds greater increases in the number of competitive states than in solid or leaning Republican states.
