Rudy Giuliani and Mike Huckabee continue to lead national polling in the race for the Republican Presidential Nomination, but they’ve switched places.
The Rasmussen Reports daily Presidential Tracking Poll for Sunday shows Giuliani with 22% support while Huckabee earns 19% of the vote. Mitt Romney and Fred Thompson are tied for third at 13% and John McCain is at 10% (see recent daily numbers). Ron Paul currently attracts 5% of Likely Republican Primary voters nationwide.
In the race for the Democratic Presidential Nomination, it’s Clinton at 38%, Obama at 27% and Edwards at 13%. Bill Richardson and Joe Biden are each supported by 4% of Likely Democratic Primary Voters while no other Democrat has more than 2% support nationwide (see recent daily numbers).
Results for the Presidential Tracking Poll are obtained through nightly telephone interviews and reported on a four-day rolling average basis. Next update scheduled for Monday at 11:00 a.m. Eastern.
Some pundits have speculated that if the two major parties nominate lesser known candidates, it might create an opening for Michael Bloomberg to mount a third party campaign. However, new polling by Rasmussen Reports in New York, New Jersey, and Connecticut shows that Bloomberg would have a difficult challenge even in the states where he is most well known.
Other polling data released yesterday shows a three-way toss-up for the lead in Michigan’s Republican Presidential Primary between Huckabee, Romney, and Giuliani. Huckabee and Romney lead in Iowa, Romney leads in New Hampshire, while Huckabee has the advantage in South Carolina.
Giuliani is now viewed favorably by 68% of Republican voters while Huckabee and Romney earn positive reviews from 62%. Thompson is viewed favorably by 61% of Republicans, McCain by 54%. Looked at from the other perspective, Thompson is viewed unfavorably by 22%, Huckabee by 23%. Unfavorables for Giuliani, Romney, and McCain all top the 30% mark.
As with all recent numbers on the Republican race, these figures reflect a remarkable surge for Huckabee. Three weeks ago, just 47% had a favorable opinion of him while 24% had an unfavorable view. New general election polling shows Huckabee within four points of John Edwards. Earlier polling showed Huckabee competitive with Democrats Hillary Clinton and Barack Obama. Huckabee leads Clinton in Arkansas.
Clinton is viewed favorably by 75% of Democrats nationwide, Obama by 67%, and Edwards by 58%. Those three are locked in a tight battle in Iowa. Rasmussen Reports will be polling the state again next week. Clinton holds a declining lead in New Hampshire but has lost her lead in South Carolina.
A summary of general election match-ups and other key stats is provided for all Democratic and Republican candidates.
Daily tracking results are from survey interviews conducted over four days ending last night. Each update includes approximately 750 Likely Democratic Primary Voters and 600 Likely Republican Primary Voters. Margin of sampling error for each is +/- 4 percentage points with a 95% level of confidence.
Rasmussen Reports provides a weekly analysis of both the Republican and Democratic race each Monday.
Each Monday, full week results are released based upon a seven-day rolling average. While the daily tracking result are useful for measuring quick reaction to events in the news, the full week results provide an effective means for evaluating longer-term trends.
John McCain 
Barack Obama
The two leading United States presidential candidates Barack Obama and John McCain are statistically tied according to the latest Day to Day Politics Poll Average. Both the 7-day average and the 10-day average show that the difference between the two candidates is within the margin of error. Barack Obama is polling at 45.8% and John McCain is at 45.1%.

The lead for Obama has dropped by 4% in the last week, two weeks after his trip to Europe. There are about 4 weeks until the Democratic and Republican Conventions and about 9% of the public is still undecided, which is a 2% drop since last week.    

The ''Day to Day Politics Poll Average'' for the past week used the ''Gallup Tracking poll'', the ''Rasmussen Tracking poll'', the ''CNN poll'', and the ''USA Today/Gallup poll''.

The battleground states of Florida and Ohio, are also showing no statistically significant lead for either of the two candidates. However, Pennsylvania shows a statistically significant lead for Obama. These three states have been key battleground states in the past two elections with the winner of two of these three states winning the White House.  

Also, according to a new national poll, white workers give Obama the edge by 10 percent (47% for Obama, 37% for McCain), even though 1/6th of this voting group is undecided. Both parties agree that this group of voters will be a key voting bloc for victory. With 92 days left until the General Election, both parties will be campaigning heavily in the three major battleground states mentioned above and among this particular voting group.
