Hotline On Call

Wisconsin Gov. Scott Walker is running neck-and-neck against a generic Democratic opponent in a new NBC News/Marist survey of the state's all-but-certain recall election released on Friday morning.

A generic Democrat holds a small lead over Walker -- 48 percent to 46 percent -- which falls within the poll's margin of error. Independents are split, with 45 percent favoring Walker and 46 percent going for the Democrat.

Voters are similarly split evenly when it comes to Walker's job approval numbers: Forty-eight percent approve of the job he is doing while 48 percent disapprove.

Former Dane County Executive Kathleen Falk is the current frontrunner on the Democratic side, but she may soon get some company in the Democratic race from another big name. Milwaukee Mayor Tom Barrett, who lost to Walker in 2010, will announce before Tuesday whether he will run. The Government Accountability Board is set to meet later on Friday morning to decide whether to certify the recall petition signatures.

Likely Republican primary voters surveyed showed more interest in the recall than they did in the upcoming GOP presidential primary in Wisconsin. Fifty-one percent said they are tracking the recall election more closely. The Democratic recall primary is slated for May 8, with a general election to follow on June 5.

Over in the Senate race, Democratic Rep. Tammy Baldwin leads a generic Republican candidate 45 percent to 40 percent. Meanwhile, 50 percent approve of the job President Obama is doing while 40 percent disapprove.
