Voter ID Laws Impact on General Election

[JFK-Democrat]

How will the new voter ID laws impact the general election? How many points will it cost Obama and in which swing and non swing states will the impact be most obvious?

My guess is as follows:

Missouri is now out of reach for Obama (3-5%) negative impact
Virginia Obama probably still wins but the state is about 3% closer
Pennsylvania Maybe a 8% lower margin out of Philadelphia and 5% statewide

[JFK-Democrat]

Now that we are in the middle of July and the race still seems tied or Obama slightly ahead. It appears that a lot more people are taking the Voter Suppression...err Voter ID Laws seriously.

Does any care to guess what the impact will be? I am really worried about Pennsylvania, I really feel that Romney could win this state if enough people are either discouraged or actually turned away from the polls.

Am I overreacting?

The NY Times is running a story about this...sorry cant post the link because my post count is low.
