From a Reuters/Ipsos poll:
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…
By region, the idea was least popular in New England, the cradle of the Revolutionary War, with just 17.4 percent of respondents open to pulling their state out.
It was most popular in the Southwest, where 34.1 percent of respondents back the idea.
