(CNN) It's down to the wire in Louisiana's gubernatorial runoff election. In the Saturday election, Democratic Gov. John Bel Edwards is trying to hold on against Republican Eddie Rispone. It's the second election in a deep red state in as many weeks that's pitted local versus national factors.

History and polling suggest it's really close, though perhaps with the slightest edge to Edwards.

Edwards is, by all accounts, a popular governor. His approval rating is north of 50% in pretty much every poll taken of the Louisiana electorate. He wins if this election is a referendum on his record.

Trump on Saturday urged Louisianans to vote for Rispone, Rispone hopes to capitalize on a trend of governor elections becoming increasingly nationalized . Republican President Donald Trump is popular in the state , and Rispone could be helped by the President's visit to the Pelican State this week.Trump on Saturday urged Louisianans to vote for Rispone, tweeting that the GOP candidate would lower taxes and auto insurance rates in the state. (Trump attempted to help usher unpopular Republican Gov. Matt Bevin to victory in Kentucky, but the governor on Thursday conceded his close loss to Democrat Andy Beshear.)

Edwards received a little less than 47%, and the Democratic candidates combined for 47.4%. Rispone got 27%, and the Republican candidates combined got nearly 51.8%.
