Since the Republican Party's strong showing on Election Day last month, Americans' political allegiances have shifted toward the GOP. Prior to the elections, 43% of Americans identified as Democrats or leaned toward the Democratic Party, while 39% identified as or leaned Republican. Since then, Republicans have opened up a slight advantage, 42% to 41%, representing a net shift of five percentage points in the partisanship gap.
The pre-election results are based on Gallup Daily tracking interviews with 17,259 U.S. adults, conducted between Oct. 1 and Nov. 4. The post-election interviews are based on 12,671 interviews conducted Nov. 5-30.
