They said the flow of voters began to slow as 9 a.m. approached.

At Prospect Mill, Rev. Ken Tipton and his wife, Vonnie are also regular voters, but said this year there's special interest in the presidential race.

Tipton, a "Ronald Reagan Republican," said the country appears to be split down the middle.

"It will be a close election. I have high hopes, but not high expectations," Tipton said.

Both Tiptons voted for same sex marriage and gaming in Maryland and proudly cast their ballots for Mitt Romney.

As many as 125,000 Harford residents, possibly more, are expected to come out and exercise their right to vote for President of the United States, as well as on several contentious state ballot questions and for their next representatives in both houses of the U.S. Congress.

There were a record 169,546 Harford residents registered to vote for this election.

The race between President Barack Obama and his Republican challenger former Massachusetts governor Mitt Romney is the main draw for most voters.

Though the national race between the two is being rated a toss-up in many polls, Romney is expected to carry Harford comfortably.

Drawing as much interest as the presidential race in some parts of the county are statewide ballot questions on same sex marriage (Question 6), gambling expansion (Question 7) and in-state tuition rates for children of illegal immigrants who attend Maryland state colleges (Question 4). There is also a referendum that, if approved, will void the congressional districts drawn by the Maryland legislature last year and mandate that the redistricting be done over by the governor (Question 5).

There are eight proposed amendments to the county charter that Harford voters are also being asked to say “yes” or “no” on, although none of the eight is considered controversial. In fact, the Harford County Council earlier declined to follow the recommendation of its charter review board and place a council term limit amendment on the ballot, which likely would have fired up some interest among the voters.

Residents of the northern and central portions of the county are expected to vote overwhelmingly for their First District Congressman Andy Harris to have a second term in the House of Representatives. Harris, a Republican, has virtually no opposition. The Democrat whose name is on the ballot, Wendy Rosen, dropped out of the race but too late for her name to be taken off the ballot.

Residents of the southern portion of the county in the Second Congressional District will choose between incumbent Congressman Dutch Ruppersberger, a Democrat seeking his sixth term, and Republican Harford State Sen. Nancy Jacobs. A win by Jacobs would be a major upset, because the district, which includes parts of three other counties and Baltimore City, has a strong Democrat base, including in Harford, where Jacobs did not run particularly strong in winning re-election to her State Senate seat two years ago.

U.S. Sen. Ben Cardin, a Democrat, is also seeking re-election, and is expected to prevail because of the statewide Democrat majority. Cardin is not particularly popular in Harford, however. His main opponents are Republican Daniel Bongino, Libertarian Dean Ahmad and independent Rob Sobhani.

There is one name on the Harford ballot guaranteed to come away a winner on Tuesday. Harford Circuit Judge M. Elizabeth Bowen won both the Republican and Democrat primaries last winter and thus appears on the ballot unopposed for a full 15-year term on the circuit bench.
