Unfortunately, Cannondale stopped making their touring bike in 2011. I guess they didn't sell enough of them and they are now making their bikes in China.
Selling enough and making the bikes in China are unrelated. Like many US manufacturers they saw an opportunity to increase profit margin on each unit by making them in a country with much cheaper production costs.
As for Cannondale not making touring bikes anymore, that is related to not selling enough. The minimal touring bikes sold did not justify the production, inventory costs of having a touring bike in the lineup.
Its hard to buy a US made bike. The most expensive 6 series Trek bikes are made in the US. The only ones. No Cannondale or Specialized or Surly bike is made in the US. Small manufacturers and custom bike makers still make their bikes in the US. And almost all components are from elsewhere.
