New CNN Poll Puts McCain/Obama in Dead Heat

A new CNN/Research Corp. poll taken yesterday and today shows Barack Obama and John McCain tied at 47% each, confirming an earlier poll indicating Obama wouldn't receive a bump in his polling numbers by choosing Joe Biden.  The narrow advantage that Obama held last month has vanished.  The CNN story credits Hillary Clinton supporters for the drop, of whom only sixty-six percent will back Obama while twenty-sevent percent of Clinton supporters will support John McCain.  The drop in support for Obama indicates their disdain with Biden's selection over Clinton.

The raw numbers:

Registered Voters' Choice for President
Obama 47%
McCain 47%
Sampling error: +/-3.5% pts
