Tuesday's campaign roundup

Today's installment of campaign-related news items that wouldn't generate a post of their own but may be of interest to political observers:

* There is such a thing as going to the well once too many times. The McCain campaign is trying to milk the Wesley Clark issue for another day of headlines, but the best McCain aides could come up with is an odd and largely incoherent whine about the Obama campaign's neglecting to tell Clark to apologize.

* The Obama campaign unveiled its second national TV ad of the general election. The ad, titled "Dignity," began airing in 18 states (14 of which supported Bush in 2004) Monday.

* I guess McCain is writing off the labor vote.

* After several days of parity, Obama has reclaimed a 5-point lead over McCain in the Gallup Daily Tracking poll, 47 percent to 42 percent.

* Bush's money men have not yet lined up behind McCain.

* Rasmussen shows McCain leading Obama in Florida by 7 points, 48 percent to 41 percent, fueled in large part by 20 percent of Florida's Democrats supporting the conservative Republican.

* Rasmussen also shows McCain leading Obama in Georgia by 10 points, 53 percent to 43 percent.

* SurveyUSA shows Obama leading McCain in Massachusetts by 13, 53 percent to 40 percent.

* Rasmussen shows McCain leading Obama in Alabama by 15, 51 percent to 36 percent.

* The NRA is investing $40 million in the presidential campaign, most of which, one assumes, will be devoted to attacking Obama.
