“…Party polarization has been a definitive trend over the last several decades, with several scholars noting it as well as the impacts it has had on the legislative process (for more detail on party polarization, see Stonecash, Brewer, & Mariani, 2003;Theriault, 2006Theriault, , 2008Theriault & Rohde, 2011;Sorensen, 2014;Gray et al, 2015).
