For the first time, the Obama campaign has reached or exceeded the important 50% mark in two consecutive polls. In fact, the three most recent polls have Obama at that level:
Gallup: 50%, 8 point lead
Rasmussen: 51%, 6 point lead
USA Today: 50%, 7 point lead
The current polling has Obama at the highest level since March.
The 50% mark is important because, if accurate, it suggests that the McCain campaign cannot be satisfied only going after undecided voters, but must agressively attempt to convert at least some voters who are already committed to Obama.
