Voters across the state go to the polls today to cast what in most counties is a one-race ballot. The issue is nominating Republican and Democratic candidates to run for the privilege of filling the U.S. Senate seat vacated when former Sen. Jeff Sessions was appointed U.S. Attorney General.

Former Alabama Attorney General Luther Strange was appointed to take the seat temporarily and is a frontrunner in the Republican primary.

Polls are open 7 a.m.-7 p.m.

If you are unsure where you are supposed to vote, you can check that information at the Secretary of State’s Alabama Votes website.

Check the status of your voter registration here.

If you get to the polls and realize your name has been moved to the “inactive” list because of this year’s voter roll refresh effort, you just need to update your information with the poll workers and they should allow you to vote.

To check your voter registration by phone or report any problems you might have voting, call the secretary of state’s election line at 334-242-7210. Or voters can call their local board of registrars’ office. A list of the state’s 67 county boards of registrars is at http://sos.alabama.gov/alabama-votes/board-of-registrars-all-counties. Jefferson County’s board of registrars’ office phone number is 205-325-5550.

You can report any other unusual activity at the polls through the Secretary of State Office’s Stop Voter Fraud Now website.

One unusual thing about this election is that it is the first one under the state’s new crossover voting ban. If you choose to vote Republican, for instance, and no candidate gets half of the votes plus one, then the top two candidates will go on the ballot in a runoff in September. If you vote Republican Tuesday, you can vote in the Republican runoff in September. If you don’t vote Tuesday, you can vote in the Republican runoff in September. But if you vote Democratic Tuesday, you cannot vote in a Republican runoff. You could vote in a Democratic runoff, though a runoff on that side seems less likely. Then in December voters go back to the polls to decide which of the two nominees, the Republican candidate or the Democrat, to send to Washington. At that point, you can vote for a candidate in either party; you are not obligated to vote for the candidate who won the primary in which you voted.
