CRANSTON, R.I. (AP) — Republican gubernatorial candidate Ken Block is proposing an ambitious plan to improve Rhode Island's fortunes with big tax cuts and a state government makeover.

Block said Tuesday that if elected he would push to cut motor vehicle taxes, corporate income taxes and estate taxes. He also wants to reduce spending on unemployment and temporary disability benefits.

Block says he would reform government by eliminating straight-ticket voting, giving the governor line-item veto power and granting the state's ethics commission more oversight over state lawmakers.

Block, a businessman who founded the state's Moderate Party, says Rhode Island's economy suffers because insider politicians refuse to take bold action.

He faces Cranston Mayor Allan Fung in the GOP primary. Democratic candidates include Clay Pell, Providence Mayor Angel Taveras and Treasurer Gina Raimondo.
