Gallup released tracking data from national daily polls conducted Jan. 22-24 that show John McCain is bolstering his front-runner status among Republicans. He has an 11 percent lead over Mike Huckabee, his closest challenger. Hillary Rodham Clinton has an even more substantial lead in the Democratic race. Her current 16 percentage point lead over Barack Obama (31 percent) is representative of her recent strength in national polling. And, her 47 percent is nearly 4 times the support trailing Democrat John Edwards (12 percent) can muster.

Among Democrats, polling results since Jan. 6, show a sizable 10 point pick-up by Clinton and 3- and 5-point losses by Obama and Edwards, respectively. In the last several weeks as tracked by Gallup, there has been no change in the order of Democratic candidates, although the outcome of Saturday’s South Carolina Democratic primary could influence national polling results.

Among likely Republican and Republican-leaning voters, McCain’s support has skyrocketed from 17 percent to 31 percent since Jan. 6. Since winning the New Hampshire and South Carolina primaries, McCain has solidified his lead, hitting a peak (32 percent) on Jan. 16. Huckabee, who had been leading McCain by 11 points in Gallup’s poll on Jan. 6, is now on the wrong end of a gap the same size with 20 percent. Romney, now at 19 percent, has picked up some support and is creeping up on Huckabee, but both have quite a bit of ground to make up on McCain.

Gallup is interviewing 1,000 U.S. adults nationwide each day. The combined data from Jan. 22-24, 2008, including interviews with 1,045 Republican and Republican-leaning voters and 1,201 Democratic and Democratic-leaning voters, have a margin of error of ‘3 percentage points.
