"I think that's why I've gotten support, not because people are happy about what's going on in the schools in terms of all these major cuts, but because they know that we've really given priorities to keeping classroom teachers in the classroom and that that's been the last thing we've attacked."Powell, a university instructor whose two children attend city schools, said he could no longer stand by as education was undermined by misguided leadership and poor decisions, such as promises of raises given in the absence of additional funding and property sales he compared to "selling your water heater to pay your gas bill."Foster, a community college teacher and administrator, cruised to victory to replace Jackson, who opted not to seek reelection.
