By MEGAN SCHRADER megan.schrader@gazette.com -Gov. John Hickenlooper received backup Wednesday from his gubernatorial predecessors, and together they pushed back against the anti-testing, anti-standards movement that has gained bipartisan traction in the Colorado Capitol.Former governors Roy Romer and Bill Owens, who faced their own education hurdles during their collective two decades in office, came out strong against attempts to get Colorado out of the tests and standards developed by a consortium of states."I think there are still a number of Republicans who support standards and assessment and testing," said Owens, a Republican who held the office from 1999 to 2007.
