Bret doesn't have the money behind him for advertising that Forrester has.
I have received one mailshot from Schundler and nine mailshots from Forrester. The one I got from Schundler was a solid platform statement. The nine I got from Forrester's campaign have been a mix of:
two (2) that focussed on a 30% property tax cut promise.
seven (7) that were a negative campaign against Schundler, and which quoted liberal news sources for its "proof" of Schundler's (supposedly) terrible record.
That Forrester would run a negative campaign against someone who might become his own party's candidate speaks volumes. That he is solidly anti-RKBA and Bret is largely pro-RKBA is also clear.
