If Santorum and kids lived in Virginia - and I don't dispute him this right, he can live anywhere he chose - his kids should be schooled in Virginia, not Pennsylvania.
"Where, exactly, does Santorum call home?
Santorum became mired in a residence controversy after stating that he spent only “maybe a month a year” at his Pennsylvania home on Stephens Lane, which is part of the Penn Hills real estate market just outside of Pittsburgh.
When he was the Pennsylvania senator, Rick Santorum and his family lived in this Leesburg, VA home.
In reality, Santorum and his family were living in Leesburg, VA, prompting serious questions about why the school district in Penn Hills was paying for his children’s online school tuition for instruction between 2001 and 2004.
Critics complained that Pennsylvania taxpayers were paying 80 percent of the tuition for five of Santorum’s seven children — who lived in Virginia — to attend an online “cyber school.” The flap forced Santorum to pull his kids from the cyber-school program, but the issue helped doom him against Democrat challenger Bob Casey, who beat Santorum by 18 points. In 2006, the Pennsylvania state Department of Education agreed to pay $55,000 to settle the dispute.
Meanwhile, since his 2006 re-election defeat, Santorum has since moved into another home in Virginia. In 2007, he spent $2 million to buy a 5,000-square foot home in Great Falls, VA, his filing papers with the Pennsylvania Department of State lists his home municipality as Fairfax County, VA.
