A new Public Policy Polling survey in Ohio shows Sen. John McCain catching Sen. Barack Obama. After two months with Obama in the lead, the race is now tied at 45% each.
Key findings: “Party unity is an issue for Obama in the Buckeye State. While McCain has an 89-7 lead with voters who identify as Republicans, Obama has a narrower 75-17 edge with Democrats. Delving deeper into the numbers, it appears that residual unhappiness from Hillary Clinton supporters could be the cause. The 25% of Democrats who currently either support McCain or are undecided are disproportionately middle aged, white, and female or in other words prototypical Clinton voters.
