Republicans put the Senate Democrats, with just slim control of the chamber, on defense across a wide map in several states favorable to the GOP.

In Ohio, Trump-backed Republican Bernie Moreno, a Cleveland businessman, is seeking to unseat three-term Democratic Sen. Sherrod Brown. Some $400 million has been spent on the race.

One of the most-watched Senate races, in Montana, may be among the last to be decided. Democrat Jon Tester, a popular three-term senator and ”dirt farmer” is in the fight of his political career against Trump-backed Tim Sheehy, a wealthy former NAVY Seal, who made derogatory comments about Native Americans, a key constituency in the Western state.

And across the ”blue wall” battlegrounds of Pennsylvania, Michigan and Wisconsin, Republicans are depending on Trump as they try to unseat a trio of incumbent Democratic senators.

Outgoing Senate Republican leader Mitch McConnell has spent a career focused on seizing and keeping majority power, but other opportunities for Republicans are slipping into long shots.

In the Southwestern states, Arizona firebrand Republican Kari Lake has struggled against Democrat Ruben Gallego in the seat opened by Sen. Krysten Sinema’s retirement. In Nevada, Democratic Sen. Jacky Rosen has been holding out against newcomer Sam Brown.

WASHINGTON — Voters said the economy and immigration are the top issues facing the country, but the future of democracy was also a leading motivator for many Americans casting a ballot in Tuesday’s presidential election.

AP VoteCast, an expansive survey of more than 110,000 voters nationwide, found a country mired in negativity and desperate for change as Americans faced a stark choice between former President Donald Trump and Vice President Kamala Harris.

Trump, the Republican, sought to define the election as a referendum on the Biden-Harris administration and blamed it for inflation and illegal crossings at the U.S. border with Mexico. Harris, the Democrat, tried to brand herself as being more focused on the future and described Trump as old, tired and a threat to the Constitution.

About 4 in 10 voters considered the economy and jobs to be the most important problem facing the country, as frustration with inflation spiking in 2022 lingered in the form of higher grocery, housing and gasoline costs. Roughly 2 in 10 voters said the top issue is immigration, and about 1 in 10 picked abortion.

But when asked what most influenced their vote, about half of voters identified the future of democracy as the single most important factor. That was higher than the share who answered the same way about inflation, the situation at the U.S.-Mexico border, abortion policy or free speech.

Those issues also outweighed considerations of recent assassination attempts against Trump or the legal cases he is facing, as well as the possibility of Harris becoming the first female president.

Trump holds an edge on economy, Harris leads on abortion

Trump held an advantage over Harris on which candidate could better handle the economy, as well as on the issue of immigration. On abortion, Harris was seen as the stronger candidate. During the campaign, Harris talked about access to abortion and medical care for women as an issue of fundamental freedom, whereas Trump said it was a matter best left to the states after the Supreme Court overturned Roe v. Wade in 2022.

WASHINGTON — A divided America weighed a stark choice for the nation’s future Tuesday as a presidential campaign marked by upheaval and rancor approached its finale.

Voters were deciding whether to send Republican Donald Trump back to the White House or make Vice President Kamala Harris the first female president. Polls closed in Georgia, one of the closely fought battlegrounds that could decide the election, along with a handful of other states. On Election Day, tens of millions of Americans added their ballots to the 84 million cast early as they chose between two candidates with drastically different temperaments and visions for the country.

Trump and Harris each notched early wins in reliably Republican and Democratic states, respectively. Trump won Kentucky and Indiana, and Harris took Vermont.

The economy and immigration are the top issues facing the country, voters said, but the future of democracy was also a leading motivator for many Americans casting a ballot in Tuesday’s presidential election. AP VoteCast, an expansive survey of more than 110,000 voters nationwide, found a country mired in negativity and desperate for change.

Those casting Election Day ballots mostly encountered a smooth process, with isolated reports of hiccups that regularly happen, including long lines, technical issues and ballot printing errors.

Harris has promised to work across the aisle to tackle economic worries and other issues without radically departing from the course set by President Joe Biden. Trump has vowed to replace thousands of federal workers with loyalists, impose sweeping tariffs on allies and foes alike, and stage the largest deportation operation in U.S. history.

Harris and Trump entered Election Day focused on seven swing states, five of them carried by Trump in 2016 before they flipped to Biden in 2020: the ”blue wall” of Pennsylvania, Michigan and Wisconsin as well as Arizona and Georgia. Nevada and North Carolina, which Democrats and Republicans respectively carried in the last two elections, also were closely contested.

Trump voted in Palm Beach, Florida, near his Mar-a-Lago club, and said afterward that he was feeling ”very confident.”
