UC Davis is not hiring two more faculty. They hired one senior faculty, Matthew Shugart, from UCSD.
The keyword here is quantitative. UCD has a very rigorous methods sequence that everyone (including theorists) must take during the first year. It is tough, and students have dropped out in the past because they couldn't handle it.
You are encouraged to cut across the traditional subfields in your research. American politics is very strong (nationally ranked in the top 20) and comparative politics will be comparable in the next few years (if it isn't already). Generally the subfield pairings are american/methods, comparative/methods, or comparative/IR, although you are welcome to choose your own combination.
