Party Conventions in the Same City in 2012?

Here's a money-saving idea making the rounds for the political parties come 2012, when we’ll be nominating presidential candidates again. Instead of trying to find a geographically correct big city with enough hotel rooms to house 4,000 delegates and media, the Republican National Committee and Democratic National Committee should pick one city and one venue for the events. Not only would it be easier to orchestrate, but the cost savings would be huge, especially to the U.S. Secret Service and media who have to set up two separate operations. It's been done before and was almost done in 2004 in New York City, but the Democrats and GOP couldn’t agree.
