The latest Rasmussen Reports polling shows that Senator Hillary Clinton (D) leads Senator John McCain (R) 46% to 42%. That’s a net loss of ten percentage points for McCain over the past month. In late May, before the immigration debate sent the McCain campaign in a downward spiral, the Senator from Arizona had a six-point lead over the former First Lady.

Clinton remains neck-and-neck with another New York politician, Rudy Giuliani. The former Mayor of New York City attracts 46% of the vote while Clinton earns 45% in that match-up. A month ago, Giuliani had a three-point lead over Clinton. Two months ago, they were tied.

Among women, Clinton leads both Giuliani and McCain. Giuliani has a six-point edge over Clinton among male voters. McCain has just a one-point lead among men. Both Republicans have a solid lead over Clinton among white voters but Clinton has an overwhelming lead among all other voters.

Other polling data shows that 29% of voters would definitely vote for Clinton if she ends up on the ballot in 2008. While that’s the highest level of core support for any candidate, Clinton is also near the top on the other side of the ledger—46% of voters say they will definitely vote against her if she is on the ballot.

Twenty-six percent (26%) say they’d definitely vote for Giuliani while 37% would definitely vote against him. The numbers for McCain are much weaker—just 16% would definitely vote for him while 42% would definitely vote against.

Clinton remains the clear frontrunner in polling for the Democratic Presidential nomination. Giuliani and McCain were early frontrunners for the Republican Presidential nomination. Giuliani remains one of the frontrunners, locked in a competitive race with newcomer and former Senator Fred Thompson. McCain, however, has fallen to the point where he is struggling to retain double-digit support.

Clinton is viewed favorably by 49% of voters and unfavorably by 48%. Her numbers have remained steady and evenly divided all year. For better or worse, the Senator from New York has been very visible on the national political scene for 15 years.
