Poll: A Dead Heat In McCain’s Home State Of Arizona

Another poll shows that John McCain could be in serious danger of losing his home state of Arizona — and remember, the Obama campaign just announced that they’ll be advertising there for the first time in the general election.

The new numbers from Research 2000: McCain 48%, Obama 47%, with a ±4% margin of error. The key number from the internals is that Obama is winning the early vote by a 54%-42% margin, and this group is expected to make up 17% of the total likely voters.

Another important number, showing McCain’s latent vulnerability: In a test run for his 2010 re-election against Democratic Gov. Janet Napolitano, McCain is trailing 53%-45%.
