Candidates are making the final big push with one week remaining before the election.  In the 6th-District this afternoon, two-term Republican Michele Bachmann and Democratic challenger Tarryl Clark debate before the St. Cloud Chamber of Commerce. Meanwhile, 5th-District Congressman Keith Ellison holds a press conference at Minneapolis City hall to promote voting and denounce voter harassment.  Tonight, the candidates for governor square-off at a debate at Minnesota State University Mankato.  That debate can be heard live on 610 KDAL tonight from 7 p-m to 8:30 p-m.  Current Governor Pawlenty will be off campaigning in eight states before the election, starting with today's stop in Texas to support GOP candidates there.
