At the present moment the GOP couldn't find it's butt with both hands....they are leaderless, feckless, candidateless, and as screwed up as Hogan's Goat.
If there is to be leadership going into November and do sensible things like you suggest, ads against taxes, the Tea Party & Conservative movement will be the ones to do it.
Unfortunately, the Tea Party & Conservative movement is leaderless - it has no focus where money can be raised to support an agenda....and it has no formalized agenda.
We have momentum - but its being dissapated in too many directions. Without a leader, Victory in November is not a given!
