Sen. Claire McCaskill (D-Mo.) recently paid a cybersquatter $4,000 for the rights to, which now redirects to her campaign website.  

The St. Louis Dispatch caught the expense listed on McCaskill's latest campaign finance report. A Missouri-based graphic designer owned the domain name, according to the paper.   

In her 2006 race, McCaskill utilized the domain name  

If recent history serves as a guide, McCaskill's campaign may have gotten off fairly cheap. Squatting on the domain names of political candidates has become a lucrative hobby for some, and URLs often end up in enemy hands. 

This past election cycle, Sen. Robert Menendez (D-N.J.), Arizona Republican Ben Quayle and former Indiana Rep. Brad Ellsworth (D) all found URLs utilizing their full names controlled by the opposing party. 

Last year, Sen. Jon Tester (D-Mont.) purchased for an undisclosed amount, according to The New York Times.
