One impact of the long run-up to Election 2008 can be seen in public perceptions of the leading Presidential candidates. After a year of campaigning with no votes actually being cast, only one candidate in either party is now viewed favorably by more than half the nation’s voters. Stunningly, especially given the status of his campaign six months ago, that candidate is John McCain. This is one reason why a recent article noted it is a good time to be John McCain.

The Arizona Senator is now viewed favorably by 53% of all voters (a total boosted by the fact that 56% of those not affiliated with the major parties have a positive opinion of him. Thirty-seven percent (37%) of voters nationwide have an unfavorable opinion of him. Last summer, following the Senate debate on immigration, McCain’s stock had sunk so low that he was viewed favorably by fewer than half the voters in his home state. But, he has recovered in the latest Arizona polling as well as nationally.

John Edwards is viewed favorably by 49%, unfavorably by 42% and Hillary Clinton is the only other candidate with favorables about 43%. She is viewed favorably by 48% of all voters and unfavorably by 50%. Attitudes about the former First Lady are held more firmly than those for other candidates.

Barack Obama earns favorable reviews from 43%, Fred Thompson from 42%, Mike Huckabee and Rudy Giuliani from 40%. Mitt Romney has the lowest total at 38%. Fifty-one percent (51%) have an unfavorable opinion of the former Massachusetts Governor. That unfavorable rating is matched by Obama and topped only by Giuliani at 55%.

Of course, entering the Primary season, it may be that opinions within the partisan ranks matter more than the overall numbers. McCain is viewed favorably by 66% of Republican voters nationwide, Thompson and Giuliani are viewed favorably by 65%, Romney by 57%, and Huckabee by 55%.

Among Democrats, Clinton is viewed favorably by 80% of Democratic voters, Edwards by 66%, and Obama by 61%.
