Why did Nebraska not vote in 1860?

Nebraska did not vote in the 1860 presidential election because it was not yet a state; it was still a territory at that time. The Nebraska Territory was established in 1854, and while it had a territorial government, it did not have the status or rights of statehood, which included the ability to participate in federal elections. It wasn't until 1867 that Nebraska became the 37th state in the Union.
