It's designed to push back the election date, and only affects the date of a recall election (general election dates are predetermined). A fake Republican beating Walker would be hilarious, but it would still only prolong his regime (granted, the Republicans would run a fake Democrat, prolonging it anyways).
A Fake Republican wouldn’t postpone the election date at all. We have several true Democrats already running in a primary, so the final recall is already set by that.
However, Wisconsin has open primaries, so voters’ party affiliations do not prevent one from voting in a primary, but a single voter can only vote in a single party’s primary in a given election. So when only one party is facing a primary, voters from the other party have some small incentive to try and sabotage that primary by voting for the weakest candidate, or even a fake party candidate. So in this case, Democracts running a fake Republican could prompt Republican voters that would otherwise try to disrupt the Democrat primary to stick with voting for their own party.
