Republican George Allen’s infamous “macaca moment” is “fair game” on the campaign trail, Democrat Tim Kaine’s campaign said Tuesday.

In a conference call with reporters, Kaine adviser Mo Elleithee said anything in a candidate’s past should get consideration from voters and didn’t close the door on the campaign addressing the issue in the months leading up to the 2012 U.S. Senate election, although he didn’t say whether the campaign intended to make it a focal point.
