Democratic front-runner Joe Biden said Monday that he plans to campaign and win in states that have almost always supported Republicans in the past four decades, including South Carolina, Georgia and Texas.

"We plan on campaigning in the South. I plan on — if I'm your nominee — winning Georgia, North Carolina, South Carolina. And I believe we can win Texas and Florida, if you look at the polling data now," the former vice president said at the Poor People's Campaign forum in Washington. "It's a marathon — it's a long way off."

Georgia last backed a Democrat in 1980 when it voted for home-state former governor and incumbent President Jimmy Carter. Carter lost that election, but he carried Georgia, South Carolina and Texas in 1976, the last time all three states voted to send a Democrat to the White House.
