Vice President Joe Biden is off to an early start in playing the traditional role of attack dog for the Democratic ticket, accusing Mitt Romney of wanting to "double down" on failed Republican economic policies.
To date, President Obama and his vice president have avoided directly confronting any of the Republican presidential hopefuls, leaving the partisan sniping to campaign surrogates and staff.
It appears that is about to change.
Writing in Iowa's largest newspaper just days before the state's leadoff caucuses, Biden says that the former Massachusetts governor "appears satisfied to settle for an economy in which fewer people succeed, while the majority of Americans are left to tread water or fall behind."
"His plan would actually double down on the policies that caused the greatest economic calamity since the Great Depression and accelerated a decades-long assault on the middle class," Biden writes in the Des Moines Register, which has endorsed Romney for the Jan. 3 caucuses.
