The latest Gallup daily tracking poll shows Sen. Hillary Clinton edging Sen. Barack Obama, 44% to 41%, "as close as they have been since the polling program started at the beginning of 2008." The three point gap is within the poll's three-point margin of error.
Key finding: "The data suggest that Obama has gained slightly more -- at least initially -- from John Edwards' departure from the race. In the final tracking data including Edwards in all three days' interviewing (Jan. 27-29 data), Clinton had 42%, Obama 36%, and Edwards 12%. Since then, Clinton's support has increased two points and Obama's five. Tomorrow's release will be the first pure post-Edwards three-day rolling average."
