Automated Workflow approval

I've set up a workflow and it sends to 2 people who can approve/decline. I have 2 questions. 1) What happens if 1 person "declines" and the other "approves". It seems in my test that the "approve" trumps and its recorded in the approval status column. Is there a way to capture both approval responses? 2) I am able to capture the "date stamp approved" but can I capture WHO approved it based on the people in the workflow?
