Niagara Gazette — Obama also turned back late moves by Republicans in Pennsylvania, Michigan and Minnesota.
Hispanics account for a larger share of the population than the national average in Nevada and Colorado, two of the closely contested battleground states. The president's outsized majority among Hispanics — in the range of 70 percent according to Election Day interviews with voters — helped him against a challenger who called earlier in the year for self-deportation of illegal immigrants.
Other factors in crucial states:
• In Ohio, roughly 60 percent of all voters said they favored the Obama administration's auto bailout, and the president captured nearly three quarters of their votes, according to the survey, conducted for The Associated Press and a group of television networks. He stressed the rescue operation throughout the campaign. Romney opposed it, and in late campaign commercials suggested it had contributed to the loss of U.S. jobs overseas.
• In Virginia, the black vote was roughly half again as big in percentage terms as nationally, also an aid to Obama.
Changes are in store for the victorious administration. The election past, three members of Obama's Cabinet have announced plans to leave their posts: Defense Secretary Leon Panetta, Treasury Secretary Tim Geithner and Secretary of State Hillary Rodham Clinton. Other changes would not be unusual in the second administration of any president.
As for Congress, Democrats improbably gained seats in re-establishing their Senate majority. Their final margin hinged on a decision by independent Sen.-elect Angus King of Vermont, who has not yet said which party he will affiliate with.
The election was the second in a row in which Republicans lost potentially winnable races after nominating candidates who articulated views that voters evidently judged as too extreme. Two years ago, tea party-backed insurgents were defeated in Nevada, Colorado and Delaware. This year, senior Republicans watched in disbelief as Rep. Todd Akin in Missouri and Richard Mourdock in Indiana flamed out after making incendiary comments about rape.
Sen. John Cornyn, R-Texas, chairman of the National Republican Senatorial Committee, said his party has "a period of reflection and recalibration ahead." In a statement issued before the extent of GOP losses was known, he added, "While some will want to blame one wing of the party over the other, the reality is candidates from all corners of our GOP lost tonight."
