Columbus, Ohio (CNN) - The White House has added yet another campaign stop in Ohio on the final weekend before Election Day, as the hotly-contested race between Democratic Gov. Ted Strickland and his Republican challenger John Kasich comes down to the wire.
Vice President Joe Biden will appear with Strickland in Toledo on Sunday night, a Strickland campaign source told CNN.
That's on top of a high-profile Halloween rally on Sunday afternoon headlined by Biden and President Barack Obama - a Cleveland stop designed to gin up excitement among the Democratic base.
The latest Biden appearance will be his third in northeast Ohio since the summer.
The White House has lavished attention on Ohio - Obama drew a crowd of 35,000 in Columbus last week, and his top political adviser, David Plouffe, recently campaigned with Strickland - a reminder of the central role the Buckeye State will play in Obama's own re-election campaign.
Obama won the state's 20 electoral votes in 2008, and Strickland recently deemed Ohio the "firewall" for Obama's re-election chances.
