Washington: Still not giving up on White House hopes, former Alaska governor Sarah Palin has said that she could yet bid for the American top slot, should the Republican presidential race lead to an open convention in August.

"Anything is possible. I don't close any doors that perhaps would be open out there", Palin said after casting her vote in Alaska's Republican caucus, commenting she might consider throwing her hat, if pressed.

"I could seriously do whatever I can to help put our country back on the right track", she said when asked about whether she planned a shot at the next Presidential elections in 2016.

If the Republican nomination could run down to an open convention in August, Palin replied, "If someone wanted to put her name in the hat. Anything is possible."

Palin has long been calling for an extended nominating process, insisting a longer primary season will more thoroughly vet the eventual GOP nominee ahead of the general election.

"I believe the competition makes all our candidates better. Remember, there are five men running for president, and I think (US President) Barack Obama is the worst choice," she said.

She added that the ideal Republican nominee would be able to "bust through" what she called "Orwellian-Obama rhetoric and pandering."
