I’ve very quickly created a Yahoo! Pipes mashup for today’s council and London mayor elections in the UK. All it does at the moment is

• take the RSS feed for Tweetscan searches for ‘election’, ‘voted’, ‘voting’, ‘vote’, ‘Ken Livingstone‘ and ‘Boris Johnson‘,
• gets rid of duplicate results,
• and spits out a feed.
• UPDATE: Now it also takes feeds from Google News and Technorati searches for local election and the two london candidates
• It also filters out anything with ‘Zimbabwe’ in it, as reports on those elections were coming through.

I’d like to invite you to clone the mashup and make improvements. Or you can just suggest them here.

Some things I’d like to do are: add images; geo information and mapping; other feeds; filtering based on user input (e.g. location).

Meanwhile, here’s how the two mayoral candidates are faring on Twitter mentions according to a search on Twist:
