国会观察者出版物网站有一些关于国会的信息(包括登记表投票)。这是个商业网站，不过看上去不错。

Congressional Observer Publications has a bunch of information (including roll call votes) about Congress. This is a commercial site, but it looks good.

网站仍然有改进的空间，但我觉得就产品推销而言，这是个不错的例子。

There's still room for improvement but I think it's a good example of a product launch website.
