Kentucky Sen. Rand Paul, a freshly announced presidential candidate, may not be a favorite to win the GOP nomination, but he may well be the front-runner in merchandising variety.
In an apparent bid to appeal to the younger portion of the electorate, Paul's store sells skull caps, phone cases, Beats headphone skins and a giant birthday card. There is even a a beer stein with an image of a dog holding an American flag under the title "UNLEASH."

"Cut the leash, defeat the Washington machine. Cheers!" the website description reads.
Also under the "Fun Stuff" category in the candidate's store is a cover for computer cameras.

"That little front facing camera on your laptop or tablet can be a window for the world to see you - whether you know it or not! Stop hackers and the NSA with this simple camera blocker. Safe and practical," the online store says of the product.
Several of the Paul products include visuals of the Constitution—including a T-shirt and an iPhone case—which is a political theme for the son of libertarian icon and former Texas congressman Ron Paul.
"I am running for president to return our country to the principles of liberty and limited government," a quote attributed to Paul says on his site—which broke the news the senator would run ahead of his scheduled midday in-person announcement.
The store even offers a $1,000 Paul-autographed Constitution. "It's hard to find a greater defender of the U.S. Constitution in the Halls of Congress than Rand Paul," the item's description says.
But the merchandise goes beyond accessories: Paul's branded clothing is "fashion for a cause," his website says.
"It's easy to be a fashion plate for the world's biggest brands. When you wear the Rand Brand, you look good and stand for something bigger than all of us ... liberty," the site boasts, adding "Thomas Jefferson would be proud."
Such fashion includes a T-shirt proclaiming "Don't Drone Me, Bro!"
Even the payment options take a decidedly contemporary twist for the Kentucky senator's campaign. In addition to credit card and PayPal choices, Paul's website allows supporters to donate in bitcoin (the cryptocurrency boasts a strong following among a subset of libertarians).
Paul starts the campaign in the second tier of GOP candidates, drawing the support of 8.4 percent of Republicans, according to a March Reuters/Ipsos tracking poll.
That puts him behind former Florida Gov. Jeb Bush, Wisconsin Gov.Scott Walker and former Arkansas Gov. Mike Huckabee, and in a statistical tie with four other candidates—Texas Sen. Ted Cruz, New Jersey Gov. Chris Christie, neurosurgeon Ben Carson and Florida Sen. Marco Rubio.
