Re-call polls don't appear to work in practice. Either the bar for re-call is too low, such that evidently popular candidates face an energy-, cash-, and time-wasting re-election campaign, or the bar is too high, because a signature-collecting campaign can never match the energy of election day. Continuous voting is (more) practical. Elected candidates would face a constant risk of being out-voted, but it's generally a very low risk, because the balance of the votes is unlikely to switch overnight - it was either foreseeable or there was some democratically-relevant scandal.
