At least one person is confident Democrats will hang onto the Senate. 

White House Senior Adviser Dan Pfeiffer told NBC's "Meet The Press" the mid-term elections are about voter turnout and not Obamacare. 

He also said the president will not delay the individual mandate for the Affordable Healthcare Act. 

Last week a Republican won a special election for a Florida congressional seat. 

Republicans claim a pushback against Obamacare helped in that victory.
