Poll: Hillary Clinton, Rudy Giuliani Remain in the Lead; Lower Tier Candidates Moving Up

The latest Zogby poll looks at the Democratic and Republican races on a national basis over the course of five polls they have taken: May 20, July 14, Sept. 16, Oct. 14, and the latest one on Nov. 17 and it shows just how much of a roller coaster ride it can be.

Back on May 20, New York Senator Hillary Clinton came in with 39%. In July she slipped down to 37% and then slipped another 2% to 35% in September. Then in October, she saw her highest level of support at 46% and right now, she is just about back where she started at 39%.

Illinois Senator Barack Obama has not had a broad range of differences as has Clintion He has remained in second place all along and has a net gain of 3% Back in May he had 24%, moved up to 25% in July, had his worse level of support in September at 21%, bounced back to 25% in October and is now at his highest at 27%. Since Clinton is back to her beginning figures and there is not much of a change with the rest of the candidates, his 3% gain has come from the voters who were once on the fence, picking him as their candidate.

Former North Carolina Senator John Edwards is the only other candidate who has ever received more than 10% support. He has an overall gain of 2%. In the first and second poll, he had the exact same 11%. In the third one, he dropped down to 10%, dropped again to 9% and has now bounced back to his highest level of support at 13%.

While his figures have remained the basically the same, New Mexico Governor Bill Richardson is now 1% higher than it was at the beginning. He started out at 2%, had two consecutive 3% polls, dropped down to 2% again and is now back at 3%.

Ohio Congressman Dennis Kucinich had gained 1%, starting out at 1%, going to 2% for the next two polls, then hitting his highest at 3% and now is back to 2%.

Delaware Senator Joe Biden is at the same place now that he was at the beginning. He started out at 2%, slipped to 1%, hit his highest at 4% and has been back at 2% for the last two polls.

Connecticut Senator Chris Dodd and former Alaska Senator Mike Gravel have never gotten over 1%.

The voters who say they do not like any of the candidates and would like to see someone else on the ballot has dropped from 3% at the beginning to 2% now.
