Idahoans are heading to the polls today for the primary election.  Polls will be open from 8 a.m. to 8 p.m.  If you plan to cast your vote you will need three things:  A photo ID, your party affiliation and your ballot choice.  That will depend on what party affiliation you declare.  If you don't have an affiliation you can register before you vote.  The Twin Falls County Clerk's office says you can find your polling place by going to Idahovotes.  Election results will be posted on many county websites as well as the state website.  You can also tune in to News Radio 1310 KLIX this evening for the latest election results.
