Some 23.9 percent of Americans polled from Aug. 23 through Sept. 16 said they strongly supported or tended to support the idea of their state breaking away, while 53.3 percent of the 8,952 respondents strongly opposed or tended to oppose the notion.

The urge to sever ties with Washington cuts across party lines and regions, though Republicans and residents of rural Western states are generally warmer to the idea than Democrats and Northeasterners, according to the poll.

Anger with President Barack Obama's handling of issues ranging from healthcare reform to the rise of Islamic State militants drives some of the feeling, with Republican respondents citing dissatisfaction with his administration as coloring their thinking.

But others said long-running Washington gridlock had prompted them to wonder if their states would be better off striking out on their own, a move no U.S. state has tried in the 150 years since the bloody Civil War that led to the end of slavery in the South.
