  abstract =     {{Amazon's Mechanical Turk (MTurk) is a crowdsourcing marketplace that offers a fast and flexible platform to solicit inexpensive and reliable participants for panel stud- ies. Because it is a cloud-based environment respondents can be re-contacted quickly and easily, which limits panel attrition and makes it possible to time survey waves around imminent and recent political events. Such features also enable researchers to embed real-time experiments in the real world, which offers improved external valid- ity. We utilize the design and data from our recent panel study conducted around the Supreme Court’s Affordable Care Act (ACA) case to discuss how we used MTurk to collect data and leverage breaking news with a related experiment. We describe our panel’s attributes and attrition, offer some practical implementation tips, and suggest some avenues for future research.}}
