It's the Sunday before election day, and a final round of polls provides cheering news for supporters of Hillary Clinton and a bit for Donald Trump, as well.
The biggest win for the Trump side was from the Des Moines Register poll of Iowa, which showed Trump leading in that state by seven points, 46% to 39%. Clinton has struggled in Iowa all year, and she notably has not campaigned in the state recently.
By contrast, the Democrats have been pouring resources, including multiple visits by the candidate and top surrogates, into Ohio, and Sunday's Columbus Dispatch poll, which has a long and good track record in the state, indicated their investment may be a wise one.
A presidential candidate needs 270 electoral votes to win the White House. Most states predictably vote red or blue, but a small handful swing either way and make up the main election battlegrounds. What does it take to win the presidency?
