Vice President Joe Biden spent Labor Day in Toledo, Ohio, campaigning with Gov. Ted Strickland, a Democrat seeking a second term in November.
It's the second time in two weeks that Biden has been in Toledo. On his last visit, he touted the U.S. auto industry.
The Associated Press reported Biden "darted across the parade route and greeted people holding political signs" at the Monday morning Labor Day parade.
Strickland is facing a challenge from another former congressman, John Kasich (R), for the governor's office. A Real Clear Politics average of the latest polls shows Strickland in trouble, trailing by 10.8 points.
President Obama follows Biden to the battleground state on Wednesday, when he talks about businesses research and development tax credits in Cleveland.
