Barack Obama is sharply falling out of favor with two segments he has relied heavily upon - women and union voters, according to data from the second of three NewsmaxZogby Tracking Polls for Florida.

This despite leading Republican challenger Mitt Romney 47 percent to 43 percent in the state, according to results compiled from polling conducted Monday, Oct. 15, through Wednesday, Oct. 17.

Obama expanded his lead to 4 percentage points in Florida, the new results show. The previous poll had him at 47 percent to Romney's 44 percent. The first survey was conducted on Sunday, Oct. 14, through Tuesday, Oct. 16.

Undecideds were tallied at 11 percent for the current results, up from 10 percent for the previous data.

The results show a complete reversal in the all-important women vote and households with a union member.

Only 42 percent of women polled said Obama deserves to be re-elected, versus 44 percent who said it is time for someone new. In the previous poll, 46 percent said he deserves to be re-elected with 42 percent saying it is time for someone new.

In union households, 38 percent said he deserves to be re-elected and 49 percent said it is time for someone new, an about-face from the previous data in which 54 percent said he deserves to be re-elected, with 36 percent saying it is time for someone new.

"It's possible women and union voters are losing confidence in Obama," pollster John Zogby tells Newsmax. "It's certainly something we are going to be paying close attention to moving forward."

Overall, when respondents in Florida were asked if he deserves to be re-elected, 44 percent said he did, tied with those who said it is time for someone new, slightly better for the president from the first round of data in which 43 percent said he deserves to be re-elected, and 45 percent said it is time for someone new.

Obama faired better among men when asked that same question: 46 percent said he deserved to be re-elected, with 44 percent holding out for someone new, versus 40 percent to 48 percent in the previous poll.

Overall approval ratings remained unchanged from previous data: 48 percent "strongly approved" or "somewhat approved" of his performance, and 48 percent "somewhat disapprove" or "strongly disapprove." The previous data held the same 48 percent for those categories.

The tracking poll has Obama leading strongly among Democrats (83 percent-9 percent), among 18-29-year-olds (71 percent-25 percent), and in the South (58 percent-33 percent).

He also leads among Hispanics (73 percent-16 percent), African-Americans (88 percent- 5 percent), liberals (91 percent-6 percent), and moderates (59 percent-29 percent).

Romney has big leads among Republicans (85 percent-9 percent), conservatives (73 percent-18 percent), 50- 64-year-olds (53 percent-34 percent), those over 65 (48 percent-40 percent), whites (55 percent-34 percent), and evangelicals (56 percent-33 percent). He also leads among investors (51 percent-38 percent).

The three-day, rolling average of 841 likely voters was conducted online. Using information based on census data, voter registration figures, CIA fact books, and exit polls, complex weighting techniques are employed to best represent the demographics of the population being surveyed.

The NewsmaxZogby Poll of Florida Likely Voters sampled 35 percent Democrats, 37 percent Republicans, and 28 percent independents; 70 percent were white, 15 percent Hispanic, and 13 percent African-American; and 15 percent were ages 18-29, 34 percent ages 30-49, 28 percent ages 50-64, and 23 percent age 65 or older.

The joint venture between Newsmax and the New York state-based pollster John Zogby will feature tracking polls in Ohio, Florida, Virginia and nationally right up to Election Day.
