MADISON, Wis. (AP) -- Candidates interested in running in six districts in the state Senate where the Republican incumbents are being targeted for recall elections have until Tuesday to file.

The Wisconsin Republican Party is actively encouraging Republicans to run as Democrats to force a primary election on July 12. That would put the general election against the Republican incumbents on Aug. 9.

Democrats are decrying the move as a dishonest manipulation of the election system. But Republican backers say this is a way for them to give the incumbents more time to prepare for the election.

The Democratic Party says it doesn't want to let Republicans decide whether there is a primary or not, so they are going to have multiple Democratic candidates to ensure there is a primary in each race.
