Election night forecast: Mostly early calls, with the possibility of delays in tight races.

While there are multiple close races across the country on Tuesday, it is not expected that any will result in the kind of protracted tabulation seen in Pennsylvania, where votes in the Republican Senate primary are still being counted. But the night could still run late in some states.

In Georgia, primaries for governor and Senate appear unlikely to be close. Harder to forecast is the Republican primary for secretary of state, where Representative Jody Hice is challenging the incumbent, Brad Raffensperger.

Similarly close races are possible in Alabama, where Representative Mo Brooks is facing challengers in the Republican Senate primary, and in Texas, where multiple runoff elections will be decided.

But none of those states have a law like the one in Pennsylvania that prevents local election officials from processing absentee ballots before Election Day. In addition, voting by mail is not as popular in states voting on Tuesday as it proved to be in the Pennsylvania primary.

Early in-person voting has surged in Georgia — accounting for more than 850,000 votes over three weeks. That should help election officials tabulate full results relatively early on election night.

But keep in mind that extremely close races can lead to prolonged counting that may extend into the morning, delaying a final call.
