Voters calling themselves Democrats or Republicans reaching record lows

From Gallup.

Overall, 42 percent over the course of the past year identified as independents, a slight drop from the 43 percent who identified as such in 2014. While Democrats maintained a small advantage over Republicans — 29 percent to 26 percent — the Democratic share is at its lowest in Gallup history.

Prior to 2015, the lowest share of Americans identifying as members of the Democratic Party came in 2014, with 30 percent. Going back to 1988, 29 percent is the lowest overall share of self-identified Democrats since the polling institution began interviewing subjects via telephone instead of in person. According to its data from 1951 to 1987, however, there was never a year in which less than 37 percent identified themselves as Democrats, making the 29 percent the lowest in Gallup’s 65 years of asking the question.

Meanwhile, the share of self-identified Republicans is just 1 percentage point above its Gallup historical low of 25 percent in 2013, dating back to 1988.
