The Cowboys left Texas Stadium after the 2008 NFL season for AT&T Stadium (opened for the 2009 NFL season) that was partially funded by taxpayers in Arlington. In November 2004, Arlington voters approved a half-cent (.005 per U.S. dollar) sales tax to fund $325 million of the then estimated $650 million stadium by a margin of 55%-45%. Jerry Jones, the Cowboys' owner, spent over $5 million backing the ballot measure, but also agreed to cover any cost overruns which as of 2006 had already raised the estimated cost of the project to $1 billion.
