During presidential elections, a candidate's home state is generally considered safe territory where campaigning for that candidate's ticket is unnecessary, with some obvious deeply partisan exceptions, such as solidly red Nebraska, the home state of Minnesota Gov. Tim Walz, the Democratic vice presidential nominee.

Unfortunately for Walz, he has failed to win over voters in most of his home state but has been dispatched again to Omaha and Nebraska's 2nd congressional district to try and secure a solitary electoral vote for Vice President Kamala Harris, according to local ABC affiliate KETV.

Unlike nearly all of the other "winner-takes-all" states that award their electoral votes to whoever wins the state's popular vote, Nebraska -- along with Maine -- divvies up its electoral votes to the winner of each congressional district, which potentially makes the Omaha district's one vote critically important for an overall victory.

Walz was in Omaha, again

Local CBS affiliate KMTV reported on Saturday that Gov. Walz made his second visit to Omaha and Nebraska's 2nd District since being picked as VP Harris' running mate in August.

Aside from the predictable criticisms of the Republican ticket of former President Donald Trump and Ohio Sen. JD Vance, Walz's event was largely focused on metro Omaha's reputation as an occasional Democratic "blue dot" in an otherwise bright red GOP-dominated state.

The governor stressed how critically important the city and surrounding district's single electoral vote could be amid possible scenarios in which it could become the deciding factor in a hypothetical Electoral College tie, where 270 votes are needed to win.

"Do the math," Walz said. "Wisconsin, Minnesota, Wisconsin, Michigan, Minnesota the rest of the states. 269, one dot makes a difference."

Omaha and the 2nd District could decide the entire election

While perhaps unlikely, it is not entirely out of the question that the 2024 election could come down to how Nebraska's 2nd District votes to break a possible 269-269 tie in the Electoral College, according to Vanity Fair.

That is undoubtedly why Gov. Walz was sent there on Saturday to help shore up Democratic support in Omaha, notably at the exact same time that the Trump campaign made a bid for the city with a campaign event featuring former Democrats-turned-Trump surrogates Robert F. Kennedy Jr. and Tulsi Gabbard.

Indeed, during a recent NBC News report, political analyst Steve Kornacki explained why winning the district was "especially important for Democrats" as he outlined "an electoral map scenario for Kamala Harris that absolutely hinges on locking it down."

That scenario involves Harris winning the northern swing states of Michigan, Pennsylvania, and Wisconsin with Trump winning the southern swing states of Arizona, Georgia, Nevada, and North Carolina, setting up a 269 tie that would be broken by whichever way Omaha and the 2nd District go.

It appears that the Harris campaign is increasingly desperate to lock down that potentially decisive vote, as it has reportedly spent more than $5 million on advertising in the Omaha area compared to just around $200,000 for the Trump campaign, according to Vanity Fair.

Harris campaign might have to return to Omaha again

As noted, and barring some exceptions, presidential and vice presidential candidates typically have little trouble winning their home states and often don't need to expend much resources or time better spent elsewhere to secure those electoral votes for their respective tickets.

That is likely the case for the GOP ticket of former President Trump and Sen. Vance, as they will likely win Florida and Ohio with little trouble, and VP Harris will certainly win her state of California. But the jury is still out on Gov. Walz and Nebraska, and it wouldn't be surprising if he or Harris is forced to make yet another visit to Omaha in the final two weeks of the election to try and nail down that potentially vital last vote.
