While previous tracking polls have included three days of polling, this final release from South Carolina includes survey interviews conducted just on Thursday, Jan. 24, and Friday, Jan. 25, 2008. This latest telephone tracking survey included 816 interviews with likely Democratic voters and carries a margin of error of +/- 3.4 percentage points.
The race is closest in the largest cities of the state, but Obama still leads there - and enjoys wider leads in the suburbs and rural areas of the state. He also enjoys solid support across ideological lines, leading among progressives, liberals, and moderates alike.
Pollster John Zogby on the Democrats in South Carolina: “Obama holds solid leads in every section of the state, and among both men and women. He has big leads among voters under age 65. Interestingly, among voters over age 65, Clinton leads him by a few points only, and Edwards is doing well.
“We are making no predictions, but on the watch list is the order of finish here. Obama leads big among moderates and liberals and among all age groups. He is back over 60% support among blacks, while Clinton and Edwards are tied among whites. Clinton returned to the state after her numbers here started to slip and Edwards started to gain. After all, he is, like Bill Clinton, a son of the South.
Overall, Obama’s lead is solid as Election Day dawns, but voters here have been fluid in their support.
http://www.zogby.com/news/ReadNews.dbm?ID=1435As Zogby says this final tracking poll now only includes two days of surveys (for 814 interviews, plus/minus 3.4%) so that means this final poll which shows Obama at 41%, Hillary at 26% and Edwards at 19% must mean that on Friday Obama had a very good day, Clinton a very bad day and Edwards stayed even because on Thursday Zogby says the numbers were for just that one day:
Obama: 36
Clinton: 31
Edwards: 19
Thursday’s polling alone had Obama leading with 36%, but Clinton was just five points back at 31% (a good day for her). Edwards came in with 19% yesterday alone. The one-day sample was not enough to draw sweeping conclusions, but it is an indicator that this race continues to change.
http://www.zogby.com/news/ReadNews.dbm?ID=1434So if it was Obama 36, Clinton 31, and Edwards 19 on Thursday and today with results from Thursday and Friday its Obama 41, Clinton 26, and Edwards 19--it must mean that between Thursday and Friday Hillary's support plummeted. Zogby doesn't give just Friday's numbers but that would seem to be the indication. If somebody who has Zogby internals has Friday's numbers that may prove interesting.
