Romney Misses Housing Bubble

At a speech at a closed Lorain, Ohio drywall plant, Mitt Romney attacks Obama:

Mitt Romney brought his fledgling general election campaign to the battleground state of Ohio on Thursday, calling out President Obama just a few miles from where the president spoke yesterday.
"This factory is empty. It is owned by National Gypsum. It was closed in 2008 at the beginning of the economic downturn. Had the president’s economic plans worked, President Obama’s plans worked, it would have been open by now," Romney said on the floor of a factory where Obama campaigned as a candidate in February of 2008.
"But it is still empty, And it underscores the failure of this president’s policies with regards to getting the economy going again," Romney said, just miles from Lorain County Community College, where the president visited Wednesday.

Hmm, I wonder why that plant is still closed?  Maybe this (from Calculated Risk):

 Maybe without a giant oversupply of houses, there would be more drywall sales.  I'm not sure how this is laid at Obama's feet, but whatever.
