This system requires voters to select among political parties on their ballot, rather than among competing candidates. The standard manner of expressing that choice is by placing an ‘x’ in the circle next to the name of the party on the paper ballot ("Stimmzettel"). There is as yet no legal basis for e-voting in Austrian elections. Voters have some ability to affect the fortunes of particular candidates on their favored party’s list by casting preference votes. When doing so, however, they may not cross party-lines. Any preference votes for candidates of another party are invalid. Austria’s version of PR thus basically remains a party-list system despite the preference-vote feature.
