Either camera will do what you want.
The most common complaint we hear is not about the video but about the microphones in Digital Cameras.
With you wanting to record political speeches, you should keep something in mind.
Digital Cameras do not have a way to adjust the microphone gain.
They are usually very sensitive, so low sounds are not that much of a problem.
But if you are too near the source of the sound, you can overdrive the microphone circuit and end up with terrible audio recording.
It is particularly bad with live music at concerts and rallies.
The only way to lower the microphone pickup is to get further from the sound source.
Any sound that is louder that the ordinary speaking volume, will likely overdrive the microphone circuit.
I'm looking for a new camera. I'm going to be using it predominantly for videos, but I want something that can take good pictures also so I'm not getting a camcorder.
I'm mostly going to be using it for recording political speeches and my three month old nephew.
I've narrowed my choices down to the Canon PowerShot SX230 and the Sony Cybershot DSC-HX9V.
The Canon has a 3.5/5 here on CNET and the Sony has a 4/5.
Both record in HD, but the Canon records at 24 fps as opposed to the full 60 for the Sony. Will that make a big difference for my purposes? I'd prefer to get the Canon because I've had two that have been excellent, and it costs $100 less, but which should I go with?
