Does a clock radio use more power in the aux mode than off mode?
I listen to my phone over the stereo speakers from my clock. If I
just unplug the phone and leave the radio in aux mode will it use more
power?

Possibly, it depends on how power-conscious the designer was. The amplifier may power down with no input signal. One clue may be to put your ear to the speakers, with no input signal, and listen for amplifier white noise. Turn the volume way up.
It may not apply to your radio, but there are very strict efficiency requirements on most modern appliances. Even wall-warts (a major source of wasted energy) are now required to limit quiescent current (no load) to mere microamps.

Most?, Washing machines & dishwashers yes, what else?
Wallwarts & TVs have quiescent power limits, but I don't remember any efficiency requirement.

Wallwarts are pointless to regulate. I often see blurbs from power
companies and other sources talking about the wasted power in power
"vampires". If you can't feel them being hot, they aren't wasting enough
power to even think about. The extra heat your brain generates while
thinking about such things amounts to more power than the wall warts waste.
In comparison, a 7 watt night lite which before LEDs were often left on all
the time, would burn your fingers if you touched it. 7 watts left on 24/7
would cost $0.50 to $0.75 a month. So if your wall wart is barely warm to
the touch it likely is well under a dime a month.

Freezers, refrigerators, dryers, furnaces & ACs, anything with a motor... all currently have or will have efficiency goals (requirements may be the wrong term) in order to get that coveted "Energy Star" logo.. and yes they seem silly in many cases. Manufacturers feel pressured to display that "Energy Star" logo.... but it does add cost and complexity, and does not generally contribute to reliability.
Wallwarts are pointless to regulate.
Agreed. I once, for giggles, did a full survey of "Vampire" loads in our house - a 3-story, 4,200 s.f. center-hall colonial built in 1890, with the usual assortment of items, LED clocks, wall-warts, stand-by systems and more.
Came in at 59 watts, or nearly-so.
59 x 24 x 365/1000 x 0.14 = $72.36. Annually. $6.03 per month.
For which I do not have to re-calibrate the televisions, re-program the tuners, reset any clocks, reprogram the boiler settings, reset the alarm clocks and much more (or less, as it happens, to be done). Yes, in some cases I need to do this after a sustained power failure, but we get blessedly few of those since Sandy (6 days).

No, it's not politics. It's a different outlook on what's important.

It isn't necessary with iron lump warts either, so that can't be the goal

Whe someone insists everyone else works for 12p an hour in the first world, that is certainly politics.
That you can afford to pay it does not mean it's not a waste.
If it were $1000/month but you were a billionaire, would you think that
was not waste?
Muliply it by the 2 million people who live near you, or the 300 million
people who live in the US.

Talk about confused, it seems to be you. What does promoting or even
requiring low power use on idle appliances have to do with paying low
wages? Nothing.
So again, it's not politics to want efficient power
use and/or low power waste.
It's a different outlook from yours on what
is important.
And no one is insisting anyone turn off appliances. They're trying to
make the applliances not waste power when they are still on, working or
idle.
