Sen. Chuck Grassley is a master of efficiency when it comes to Twitter, and in just one tweet has managed to invite three gun manufacturers to Iowa and tout the state’s business-friendly atmosphere.

Texas Gov. Rick Perry is a bit more leisurely in his tweets; each manufacturer gets a separate but similar invitation: come on down!

Competition for gun manufacturers is heating up, with Maine Gov. Paul LePage extending his hand via an opinion piece in the Wall Street Journal.

Writes LePage:

We are dismayed to see strict anti-gun legislation in states that are home to some of our country’s best firearms manufacturers. Beretta USA Corp. in Maryland, Colt Manufacturing Co. in Connecticut and Magpul Industries in Colorado are facing hostile—and hysterical—legislation from politicians who slap them in the face for providing their states with jobs, opportunity and revenue.
