Thanks for the comments guys, very helpful stuff. Some notes/questions:
onClick Dropdown
While I agree one click is better than two -- not all browsers support JavaScript and I've designed the page to function without requiring JavaScript support. Unless you guys know of a way to offer both an onChange/onClick option and a button at the same time, I don't want to turn any non-JavaScript users away. Oddly, onChange does not work if there's a submit button present. Any ideas?
Color Scheme
I have received this suggestion a number of times, and I plan to put together an alternate "white" theme for those who prefer black on white. I was going for a "political underground" feel for the design, though I am not much of a web designer (as you could probably tell).
Simplifying PartySelector Page
Ok, I've already cleaned up the party selector page. I'll put much of the additional explanatory info in a secondary page, maybe a popup. Something like that... thanks for the tip there. I was thinking people might over look the dropdown, but it's good to have people cofirm that for me.
800x600 Form Factor
The page should fit into 800x600, as I've tested it numerous times at that resolution. If there's a page that doesn't fit into that resolution please let me know and I'll go about fixing it.
Again, thanks for your very helpful comments and suggestions.
