Election day is Tuesday and voters are getting fired up.

Alabama Secretary of State John Merrill, the state's top elections official, said Monday morning that he expects about 25 percent of registered voters to cast ballots in the state's Senate election between Democrat Doug Jones and Republican Roy Moore.

While that can also be viewed as 75 percent of state voters passing on the election, Merrill has increased expected voter turnout by more than 33 percent over the past two weeks. He previously said he expected only about 18 percent of registered voters to cast ballots.

It would also mark a higher turnout than the 18 percent who turned out for the Senate primaries in August.

"I raised it up after I started seeing the numbers from absentee ballots," Merrill told AL.com. "For example, in Tuscaloosa County, we have six times the number of absentee ballots that we had in the primary and/or the runoff. We went from 200 to almost 1,200.

"I think it's because more people are becoming more energized about the race here at the end and they want to make sure their vote is counted."

Which way those votes will be cast, though, remains wildly unpredictable. While polls on the race between Jones and Moore have been all over the place, the past week has been even more bizarre.

On two different days, polls have been released - one showing Jones with the lead, another showing Moore with the lead.

That latest occurrence was Monday when the poll leads for both candidates would appear to make them strong favorites heading into election day. A Fox News poll had Jones ahead by 10 points while an Emerson College poll had Moore ahead by 9 points.

Both candidates will have one final rally on Monday night to grab those voters making their decision at the last minute or to reach out once more to supporters.

Jones will hold a rally in Birmingham with Mayor Randall Woodfin and a yet-to-be-named special guest. Moore will hold a rally outside Dothan with former White House chief strategist Steve Bannon and Texas Congressman Louis Gohmert.

But the campaign strategies of the two candidates have been decidedly different. Moore has made only occasional public appearances across the state during the campaign and has opted to speak to audiences in smaller, rural settings. Even before the allegations of sexual misconduct were made against Moore, he had a sparse presence on the campaign trail.

Moore has repeatedly denied the allegations.

Jones, meanwhile, has been in front of voters at events almost daily for weeks. According to data from his campaign, Jones has attended more than 227 events over the past two months and traveled more than 8,100 miles. Campaign volunteers have made more than 1.2 million phone calls to voters in the last seven weeks and the campaign has knocked on more than 300,000 doors during the last seven weeks, including more than 80,000 last weekend.

"Our campaign is running an unprecedented Get-Out-The-Vote program, the largest in Alabama in at least a generation," campaign spokesman Sebastian Kitchen said in a statement Monday. "Doug is traveling from one end of the state to the other talking to voters about bringing both sides together to focus on issues that matter to working families, from good paying jobs to affordable health care."

Weather doesn't appear to be a factor, perhaps a stroke a good fortune given the timing of the election. No rain is expected anywhere in the state with temperatures ranging from the low 40s in north Alabama to the lower 60s in south Alabama.

Meanwhile, a problem has emerged with some college students not receiving their absentee ballots, according to Nancy Worley, chair of the Alabama Democratic Party. In a Sunday press release, the Alabama Democrats outlined the cases of three students who have not received their ballots.

"It is unacceptable to deny any Alabama registered voter the opportunity to participate in the democratic process this December 12, regardless of the various excuses that have been provided to explain why absentee ballots were not timely delivered," Worley said in a statement. "The state of Alabama comprises 61 colleges and universities, with over 81,000 students from Auburn, UAB, and the University of Alabama alone.

"These students diligently completed the legal process for absentee ballots, and their votes must be counted. They deserve immediate answers and solutions from Alabama leaders, at both the state and county levels."

Merrill said those wishing to vote via absentee ballots have had a large window with which to secure those ballots.

"Absentee ballots have been available since Oct. 18, which is almost two months that they've been available," he said.

Speaking specifically of college students, Merrill said, "Realistically, every institution in the nation, every institution of higher learning in the nation, closes during Thanksgiving. So there was a time during Thanksgiving that if you had not gotten your absentee ballot and if you were at home, you would have had the opportunity to vote absentee at that point. Or you could have made sure that your ballot was sent to the location of your choice so you could have properly processed your absentee ballot."
