You're not getting into DCA. 737 int'l base closed eff Oct 1st generated almost 90 displacements in a base of about 270 pilots and forced almost 40 guys to leave the base.
There are FO's, as well as CA's, displaced out of DCA. Until they are recalled you cannot bid into DCA. It doesn't matter if you're the #1 pilot at AA, until the displaced guys are reinstated you will not get a DCA bid.
