Here's something we didn't get to last week in the world of Wisconsin recalls:

Democrats who filed challenges last Thursday to recall petitions filed against three Democratic senators broke down the number of signatures collected in each of the campaigns by out-of-state circulators. Such signatures accounted for more than 44% of those collected by the recall campaign against Sen. Dave Hansen (R-Green Bay), Democrats say.

According to a Republican Party campaign finance statement filed last month, the party spent $92,000 on a Colorado firm, Kennedy Enterprises, to provide staffing for several recall campaigns. On its website, Kennedy Enterprises lists circulating petitions as one of the services it provides.

A Journal Sentinel spot check of Hansen recall signatures found that more than 150 of the 200 pages of signatures checked were circulated by people with out-of-state addresses.

But recall organizer David Vander Leest said the true proportion of signatures collected by out-of-staters was closer to 50%. And the Democratic analysis backed him up.

The Democrats said 44.65% of the signatures against Hansen were collected by out-of-staters, while the out-of-state proportion in the campaign against Sen. Jim Holperin (D-Conover) was 36.64% and of the campaign against Sen. Robert Wirch (D-Pleasant Prairie), 33.12%.

Democrats say some of the out-of-state circulators misled petition signers about what they were signing, and argued in their challenges to the petitions that anything these circulators collected should be thrown out.

The Republican responses to the Democrats' challenges are due Thursday.

Vander Leest emailed a statement Wednesday saying that his recall committee "believes this challenge is being launched to silence the voice of the people of the 30th Senate District, by a disgruntled Senator who is on the wrong side of public opinion."

Also due Thursday: Democrats' response to a challenge by Sen. Alberta Darling (R-River Hills) to recall petitions filed against her. Her challenge, like those of four other Republican recall targets, claims that discrepancies between the two documents that launched the recall were enough for the state to throw all the signatures out. In other cases, Democrats have argued that the challenge is trivial because those first two documents were filed at the same time.
