Reading between the lines...

From the latest Brady Campaign E-mail:

Our winning strategy this year will be to focus on targeted electoral campaigns. By strategically directing our energy, efforts, and resources on the races where we can have the greatest impact, your generous contribution today will help us seize this chance to put our stamp on the 2008 elections.

Translation: We have so few resources available we can only focus on the races we know we can win and that have an NRA endorsed candidate in opposition. This way we can tout we had lots of victories in 'endorsed' campaigns while ignoring the trouncing of our ideology elsewhere. Just like we did in 2006.
