WASHINGTON (AP) — A conservative super PAC has jumped back into the Indiana Senate race with a nearly $1 million ad buy highlighting Democratic nominee Joe Donnelly’s support for two of President Barack Obama’s policies.

The Indiana buy is part of more than $6.4 million worth of air time that Crossroads GPS and American Crossroads bought this week in six Senate contests, according to Federal Election Commission records. The money also was dedicated to races in Florida, Ohio, Virginia, Nevada and Wisconsin.
