GOP Identification Dips
Jeffrey M. Jones at Gallup:
Forty-four percent of U.S. adults identify as Democrats or are independents who lean to the Democratic Party, while 37% are Republican identifiers or leaners. Democrats have maintained an edge of between five and nine percentage points on this measure of party affiliation throughout 2017, after holding a narrow advantage in late 2016.
The latest figures, from Gallup Daily tracking interviewing throughout November, are based on interviews with more than 14,000 U.S. adults.
Democrats' edge has expanded this year mainly because of a decline in Republican affiliation. A year ago, 44% of Americans identified as Democrats or leaned Democratic, the same percentage as now. However, Republican identification and leaning is five points lower than it was a year ago. More Americans now say they are nonleaning independents (14%) or do not have an opinion (5%) than did so in November 2016 (10% and 4%, respectively).
