I know mushy Bilbray is being pushed by the party and area Congressmen. Howard appeals to rabble-roused conservative activists. Morrow is conservative but not the loud activist that Howard is; he was considered Howard's political mentor at one point.
Others are wasting their money, imho. There are some claiming to be conservative, one whose record sounds like Duke (pushing Vietnam pilot service), some who have no chance of being known well enough to make it, and some who just annoy. The glossy ads go right to the recycle bin and I hang up no matter which candidate's recorded message it is.
Loud activists are what we need.
Go Kaloogian!!!
