I don’t know if they’ll have a choice. Once the US Supreme Court rules on the DC gun ban, I can’t imagine that the 2nd amendment won’t become a major campaign issue. If the McCain camp was smart, they’d immediately start hammering Obama on his past support of every gun ban under the sun as soon as that ruling comes down and puts the 2nd amendment in the news.
“If the McCain camp was smart...” Hammer Obama? That would be racist.
