I guess now we'll see whether state Rep. Daryl Metcalfe, R-Butler County, arguably the Legislature's most conservative lawmaker, is about politics or principle.
You may recall that Metcalfe called for -- and actually held a legislative hearing about (he's chairman of the House State Government Committee) -- impeaching Democratic Attorney General Kathleen Kane for her refusal, announced last July, not to defend the state's ban on same-sex marriage.
Well, now that a fellow-Republican, Gov. Tom Corbett, has also declined to (further) defend the ban after it was struck down this week by U.S. District Judge John Jones, I guess Metcalfe will schedule another impeachment hearing.
After all, if Kane's decision was a violation of the Commonwealth's Attorney Act, as Metcalfe claims, certainly Corbett's decision falls under the same principle: he's legally bound to defend state laws.
