Voter Turnout:  The percentage of the voting eligible population which voted in a state's U.S. House elections (as opposed to statewide and presidential elections).  We use population estimates by Professor Michael McDonald at George Mason University.  His figures estimate the number of voting age adults who are eligible to vote, which means they excludes non-citizens and ex-felons in states that disenfranchise them.
