The first and last articles show that Wallace and Baier are registered Democrat and Independent, respectively. The second "article" is just a website of random people on the internet answering questions.
So of the 3, you've shown Wallace is a registered Democrat (if you read the article you'll see it's for practicality reasons), Baier isn't a Democrat, and you have no evidence that Smith is a Democrat and no evidence that any of the 3 are liberal. But thanks for giving it a try.
