Vice President Joe Biden is flexing his political muscles on the campaign trail as he continues to help Democratic candidates running for office in November.

On Monday, Biden was in Chicago where he made time to attend an event with Gov. Pat Quinn, D-Ill. On Tuesday, Biden attended an event with Maryland Democratic candidate for governor Anthony Brown.

Biden is getting the call on the trail because of President Obama's low approval ratings. Currently, Obama's approval rating is in the low 40s.
