48% and Growing
"Democrats made gains in party identification on the national level and more U.S. states had Democratic leanings in 2005 than any time in the last four years.
Gallup conducted more than 42,000 interviews in its multi-day polls in 2005, and asked each American who was interviewed whether he or she identified as a Republican, independent, or Democrat. If respondents identified as independents, Gallup asked whether they leaned more toward the Democratic or the Republican Party. The large number of interviews allows for an analysis of partisanship at the state level, which Gallup has done in each of the last four years.Overall, in 2005, basic party identification was even -- 33% of Americans each identified as Republicans, independents, and Democrats. When independents' leanings are taken into account, the Democrats gain an advantage -- 48% of Americans either identified as Democrats or leaned to the Democratic Party, while 43% identified as Republicans or leaned to the Republican Party. That represents the largest Democratic advantage since 2000.
Additionally, the number of states where the Democrats hold an edge in partisan identification grew last year for the second year in a row. Twenty-eight states plus the District of Columbia now have a Democratic advantage in party identification of more than three percentage points, while 14 have Republican advantages, and six can be considered competitive (Gallup does not normally interview in Alaska and Hawaii).
In 2002 and 2003, more states had Republican advantages than Democratic advantages."
