Pawlenty is still effectively Catholic and converted for his wife.
Kasich is barely religious.
Pretty sure Kasich, like Pawlenty and Rubio, is Catholic convert to Evangelical Christianity. Kasich's famous blow-up with big donors involved him citing religious reasons for pushing through the Obamacare Medicaid expansion.
I'm not sure whether you'd describe it as "evangelical" - he's a member of the ACNA, a group that split off from the Episcopalians as part of the Anglican realignment. Most folks classify them as "evangelical", but I understand the worship service and a lot of the theology isn't all that different from the (very, very) mainline Episcopal Church - mostly they're just called evangelical because they represent a conservative faction splintering over some hot-button social issues.
