Wisconsin's gubernatorial recall election Tuesday is shattering campaign spending records, according to new study by the nonpartisan Campaign for Public Integrity.
The group found that more than $63.5 million, much of it from out of state sources, has been spent on the race since November. About $37.5 million was spent on the 2010 gubernatorial race.
Turnout was reported heavy Tuesday, as Gov. Scott Walker, a Republican, faces Democratic Milwaukee Mayor Thomas Barrett.
The center found that Barrett has received about 26 percent of his $4 million in campaign donations from outside Wisconsin. Walker has raised about two-thirds of his $30.5 million contributions from out of state, according to campaign filings released May 29.
The center said Walker has outraised Barrett 7 ½ to 1 since late 2011.
