Caldwell is constantly campaigning and all he cares about is the campaign, that's why he has raised millions in pay to play from Mitch Imanaka.  I'm not surprised he has another ad, money is nothing to him.  Maybe he'll have a lot more commercials, but more will only hurt him because we are all so sick of seeing him lie to us.  

CALDWELL has FAILED at RAIL.
CALDWELL has FAILED at ETHICS.
CALDWELL has FAILED at HPD.
CALDWELL has FAILED at HOMELESSNESS.
CALDWELL has FAILED at PARKS.
CALDWELL has FAILED at INTEGRITY.

That is why we need someone that we can trust.... DJOU is the only answer.  I know he doesn't have the millions of dollars like Caldwell, but oh well...I hope he can win because he's more trustworthy.  I can't stand having our money wasted all over the place, especially on rail.  Also, I think Djou will be able to put Ernie Martin in his place, unlike Caldwell.  Martin needs to go too because he's not trustworthy either, too bad he's not up for election this year.
