WASHINGTON (CNN) - Republican Sen. John McCain is slipping in polls in his home state of Arizona.
According to a new survey from the American Research Group, Sen. McCain had previously polled at 45% in February, and is now at 32 percent in July. His decline appears to be tied to the rise of former Tennessee Sen. Fred Thompson, who has not yet formally announced his candidacy for president.
Sen. Thompson received 15 percent of the votes among likely GOP voters in the new poll.
