All of these minor issues popping up to cause scrubs, anything to do with low flight rate?

All updates to the hotline...
Not sure about turnaround now.

Would imagine it will have to wait until after STS-133 launches, while this Delta II is in California the Eastern Range still supports west coast launches.

Will hang around for the official statement (trying to sleep shift back to GMT for 133) - ULA communications are very good at turning around statements.

What rocket components have a limited shelf life? Of course outdoor equipment exposed to the elements might degrade in a subtle manner and fail when stressed after a layover.
I've noticed that a Soyuz always leaves on time after the choo choo tugs it out to the pad.

Delta II COSMO - SkyMed 4 Mission Rescheduled for Nov. 2
Vandenberg AFB, Calif., (Nov. 1, 2010) - The launch of Delta II COSMO-SkyMed 4 (Constellation of Small Satellites for Mediterranean basin Observation) mission has been rescheduled for Tuesday, Nov. 2 with a launch time of 7:20 p.m. PDT. During the terminal launch countdown Monday, mission managers noted an insufficient flow of Gaseous Nitrogen in the Delta II engine compartment. Gaseous Nitrogen is used to ensure that critical components in close proximity to cryogenic propulsion systems are kept warm.
To allow engineers the time required to correct this issue, the launch attempt is delayed 24 hours. Updates to the COSMO SkyMed-4 mission status will be issued as new information becomes available. United Launch Alliance provides the Delta II launch vehicle and mission services under a commercial launch service contract administered by Boeing Launch Services for Thales Alenia Space-Italia (TAS-I).

Lots of things. For example, anything with batteries would be a candidate for limited life or needing special processing after a set period of time. (not that there is any indication of that being at play here).
The limited life items start to be really problematic if the slips start taking big jumps of calendar time. This is part of how, for example, one launch campaign I recall spent a year sitting at VAFB until it went.
We'll have to wait and see now what range availability and the outcome of the scrub creates in terms of the next available launch attempt.

soft goods on the second stage that are exposed to the hypergolic propellants.

And in case anyone didn't understand that, Jim means seals & the like.

I've noticed electrical/electronic equipments that haven been regularly activated do not receive routine servicing and are prone to intermittent problems after a prolonged layover.
Customarily, they degrade as contacts associated with switches and connectors gradually become resistive. Even those bayonet locked sealed connectors occasionally are problematic. Card edged connections are notorious.
We all know batteries self discharge so I'd think fresh batteries are installed prior to launch.

Vandenberg AFB, Calif., (Nov. 2, 2010) - An United Launch Alliance Delta II rocket with the COSMO-SkyMed 4 (Constellation of Small Satellites for Mediterranean basin Observation) mission sits poised ready for launch on its Space Launch Complex-2 launch pad here. The Delta II is set for liftoff at exactly 7:20:05 p.m. PDT with a one second launch window. COSMO-SkyMed is an end-to-end Earth observation dual-use (civil and military) system comprised of four medium-sized satellites and supporting ground stations for orbit control systems and data reception and processing. United Launch Alliance provides the Delta II launch vehicle and mission services under a commercial launch service contract administered by Boeing Launch Services for Thales Alenia Space-Italia (TAS-I).

ULA:
Due to the nationwide television coverage of the mid-term elections, broadcast satellite time is not available tonight to broadcast the launch of the Delta II COSMO SkyMed-4 launch live.
Might have to swallow some pride and tell you all to go to SFN, as they are on KSC grounds and can have ULA resources hooked up to get some updates. We'll see how it goes.
Remember, we can't copy and paste SFN updates, as they will be copyrighted.

SFN had live video before the webcast started the last two attempts, So hopefully they'll have it again.

If it launches tonight I'll be so upset...don't have my company laptop for a live feed. ugh.
Relying on you fine people for live coverage

I feel your pain but if it
doesn't launch tonight, I'll be upset!
After the push back on Fri, and the last 2 scrubs, I'm getting tired of standing on top of my A/C to get a good view/photo of it 10 minutes beforehand.
Well, getting ready to head out in a bit. Man, hope this is nothing like last night....if so the phone is going to get thrown (only because the camera is too expensive!
)
If I get a decent shot, I'll post it. Its been trial and error lately...
