Obama's approval has slipped among key parts of his coalition — the women, youth and Latino voters most responsible for putting him into office

Women surveyed said that they disapprove of Obama by a 50% to 44% margin — nearing an all-time low in the poll. It’s almost the reverse of the 55% to 44% breakdown for Obama among female voters in 2012, according to exit polls. His approval rating among women has slipped four percentage points from a year ago and 16 points since his second inaugural in January 2013, when his approval was 60% among the group. Among younger voting-age Americans, Obama’s approval rating stood at 43%. That marked an 11-point drop since June 2014 among those 18 to 29 years old. Voters younger than 30 supported Obama by 60% to 37% in 2012. Meanwhile, support for Obama among Hispanics stood at 57%t, which is down markedly from the first half of 2013, when approval among Latinos soared to about 75%. Obama’s support remains solid among African Americans, with 87% approving of his job performance. That is a modest erosion from the 93% of black voters who supported his reelection.
