Democracy for America (DFA), a Democratic activist group founded in 2004 by Democratic National Committee Chairman Howard Dean, is telling supporters to drop AT&T and switch to its own wireless phone service.

In an email to supporters today, DFA posed its wireless service as an alternative to AT&T, which donated to President Bush's presidential campaign in the 2000 and 2004 election cycles.

"AT&T must have thought that electing and re-electing Bush/Cheney was good for business. But it wasn't good for you and me. And it definitely wasn't good for the country or the world," Democracy for America Finance Director Rachel Moss wrote in the email.

"Switch to a phone service that shares your values," Moss wrote. "Join DFA Wireless, brought to you by our friends at CREDO Mobile and Working Assets."

AT&T donates to candidates from both major parties, but it favors Republicans; 63 percent of AT&T's contributions went to GOP candidates from 2000 to 2008.

DFA's service, dubbed DFA Wireless, was launched in January and funnels 10 percent of its revenue to DFA.

DFA is partnering in the effort with Working Assets, a progressive group that offers products and services and donates revenue to progressive causes. DFA Wireless will be "powered by" Working Assets' CREDO Mobile phone service, according to DFA, and will presumably use infrastructure CREDO already has in place.
