Democrats say they are filing 1 million signatures on the recall Walker petitions...

... which are due today. With only 540,208 needed, they'll have to find an awful lot of invalid signatures if a recall election is to be averted.

The paper petitions, weighing 1.5 tons, were delivered by truck to the state Government Accountability Board's office two blocks from the Capitol in Madison. The board, which runs state elections, will then take them to a secure state building that will be guarded by Capitol Police until all the petitions are electronically scanned over several days.

Next begins the months-long process of reviewing the petitions. If the accountability board determines enough valid signatures have been filed it will call elections, which may occur in June or later.
