The Center for Responsive Politics has tracked the political contributions of employees at some of the nation’s largest retailers. When you break down the data, it provides shoppers a virtual guide on where to spend if you care whether the checkout lady agrees with your political views.

So let’s crunch the numbers and let you know which red/blue shop gets your green:

Democrats corner the book market, with 100 percent of employee contributions at Barnes & Noble and Borders in the last year going to Democrats.

But Republicans have the box store employees pretty firmly on their side: Home Depot, Target, CompUSA, Macy’s, OfficeMax, Wal-Mart and Best Buy. Dems, on the other hand, merely have Circuit City, Costco and Sears.

Democrats have Bed, Bath and Beyond, but the GOP’s got Linens ’n Things in its corner. Interestingly enough, the presidential candidate who has received the most contributions from both of these “spruce up your home stores” is Rudy Giuliani. Perhaps they’re looking for some business from him and his new wife, Judith.

In other stores: Hallmark employees go for Republicans, while Toys “R” Us and the Gap are turning their hard-earned cash over to Democrats.

This latest data doesn’t bode well for Republicans: During the 2006 election, 58 percent of employees’ and political action committee contributions in the retail industry went to Republicans. But, so far this year, Democrats have snagged 52 percent of the industry’s $6.9 million in contributions.
