Barack Obama's vice presidential vetting process has moved into a new stage in which a larger than previously reported group of candidates is being exposed to a "deeper dig" into their backgrounds -- in the words of a source familiar with the process.
The hard vetting involves follow-ups to lingering questions about candidates' backgrounds and clarifications of their stands on issues. While the process is intensifying, the fact that the number of potential candidates still being considered is larger than generally believed, suggests that no decision is imminent, just 26 days before the opening of the Democratic National Convention.
It also runs counter to much-publicized comments by Virginia Gov. Tim Kaine Tuesday that "there has been a long list. It seems to be getting shorter."
