Wisconsin: Democrats Senate Majority in Jeopardy as one Senator quits caucus

Just after taking control of the state Senate, further trouble for the Democrats in Wisconsin. State Sen. Tim Cullen quit the Senate Democratic caucus due to being snubbed on the committee assignments. Cullen said he will be an independent but has not left the Democratic Party (and won't become a Republican).

Both parties suggest that there is no loss majority yet. Regardless, one Republican Senator is resigning to become Walker's deputy chief of staff, so the majority will be 16-15-1.
