Back in the early days of the Internet when folks were using dial up connections and AOL, some said that if you were smart, you would buy website domain names associated with your name. I never did, but I'm thinking some folks running for the office of President of the United States wish they had. Let's take a look at the shenanigans.
Jeb, you blew it! JebBush.com redirects to Donald Trump's Presidential candidacy website DonaldJTrump.com. Sneaky, sneaky, Mr. Trump. Bush's election website is Jeb2016.com. JebBush.org and JebBush.net both are just ads.
So DonaldJTrump.com works fine and DonaldTrump.com and Trump2016.com redirect to it. DonaldTrump.net is not currently functioning. DonaldJTrump.org is owned by someone that espouses immigration reform.
Navigate to TedCruz.com and you'll see a large black box with the statement "Support President Obama. Immigration Reform Now!" Ted, ya blew it! Cruz's actual election website is www.tedcruz.org. TedCruz.net is just ads.
ChrisChristie.com is Christie's candidacy page; he ended his campaign on February 10th. ChrisChristie.net belongs to Chris L. Christie, a Certified Mortgage Planning Specialist from what appears to be New York. ChrisChristie.org redirects to ChrisChristie.com.
CarlyFiorina.com redirects to CarlyforPresident.com, which is, or I should now say was, indeed Fiorina's candidacy website (she also withdrew on February 10th). But someone else grabbed CarlyFiorina.org, which indicates: "Carly Fiorina failed to register this domain. So I'm using it to tell you how many people she laid off at Hewlett-Packard. It was this many:" Then proceeds to display 30,000 :( frowny faces, ending with "That's 30,000 people she laid off. People with families." CarlyFiorina.net is under construction.
Former candidate (he withdrew February 3rd) RandPaul.com is indeed Paul's candidacy page, with both RandPaul2016.com and Paul2016 redirecting to it. RandPaul.org redirects to the website of the "American Solidarity Party," the "only active Christian Democratic party in the United States." His name is not mentioned on the site. RandPaul.net just has ads.
MarcoRubio.com is Rubio's site and he is the only candidate who owns and redirects both the .net and .org domains to his .com site. Nicely played, Marco! Someone named Amber Butler owns Rubio2016.com as a speculative play.
BenCarson.com, MikeHuckabee.com, JohnKasich.com and BernieSanders.com are the candidates' sites, whereas the .net and .org domains are not connected to them. Carson2016.com, Huckabee2016.com, Kasich2016.com and Sanders2016.com are all owned by domain squatters.
HillaryClinton.com is indeed Clinton's campaign website. In December 2015, HillaryClinton.net brought up a full screen image of Trump, Hillary, Bill and Melania, all smiles, with a text overlay of "$ Special Interest Group." As of February 2016, however, HillaryClinton.net redirects to donaldjtrump.com. HillaryClinton.org is a bunch of ads...don't click it. Hillary2016.com is a commentary website not associated with Clinton.
