Donald Trump Hat

Most presidential hopefuls, from Donald Trump to Rand Paul, have bustling online stores full of merchandise that lets everyone know where you (the buyer) stand. Only American citizens can purchase the shirts, cups and buttons -- because they count as campaign donations -- but is the merchandise itself American?

Hillary Clinton's robust store proudly announces every item is either "made in America," "union made" or a combination of both. Going further, Clinton's shirts are manufactured by Hauppauge, New York's Royal Apparel, according to Bloomberg Business. Royal Apparel has clothing that is made in the U.S., union-made or imported. The manufacturer uses domestic and imported cotton in its fabric. Interestingly, only five apparel manufacturers were used for the candidate apparel. American garment production has decreased significantly since 1990 with the industry losing 750,000 jobs over 21 years, Bloomberg reported.

In addition to Royal Apparel, candidates' merch comes from American Apparel (Mike Hucakabee), Port and Co. (Rick Perry), Union Line (Bernie Sanders) and Bayside (Marco Rubio, Ted Cruz and Rand Paul). "American Apparel employs over 10,000 people worldwide. Most of those jobs are right here in the USA. Our team of sewers, shippers, cutters, dyers and creatives accounts for more than 6,500 employees at our L.A.-area factories alone," states the company.

Port and Co., owned by SanMar, has a range of products that may not be manufactured in the U.S., but they do have an "All-American Tee" that features domestic sewing, fabric and cotton. Sanders' shop is stocked with only union-made items. The shirts are from a small company founded in 1907 and the stickers and signs feature a "union label."

Almost every candidate has a campaign store. George Pataki, Ben Carson, Chris Christie, Carly Fiorina, Lindsey Graham and Rick Santorum are among the candidates that do not have online stores.

The Alliance for American Manufacturing has a good rundown of all the American-made products. Every candidate with an online store is doing a great job of featuring U.S.-manufactured products, but there is still some room for improvement. None of the items on Jeb Bush's store are designated as American-made. Not all of Paul's products are made in America, so the store had to revise its descriptions from the previous "100 percent American" stance. Huckabee, Perry and Scott Walker have a few items that are not made in America.

Despite Trump's suits being made overseas, his campaign products are made in America. Yes, you can be the envy of everyone with that "Make America Great Again" hat and know you're keeping jobs in the country.
