So am I.\"My message to them is simple: this is your chance - your one chance - to save the centre-right movement in Scotland and turn us from a party which loses all the time into one which starts to win.\" Order of preferenceRuth Davidson, a newly elected Glasgow list MSP, said she believed fresh policy thinking and hard work could result in success.She said: \"I am hugely encouraged by the reception I have received from those members at the coalface who share my absolute belief that with the right kind of change the Scottish Conservatives can become a formidable force in Scottish politics and Scottish life once again.\"They share my belief that this is a real, once-in-a-lifetime opportunity to build, not to destroy.\"Jackson Carlaw said he offers the necessary maturity and experience.\"We cannot unite the party by dividing it as those, who believe that the answer to all our problems is to disband, disown our heritage, trash our achievements and say we can never win again, have chosen to do in this campaign, \" he said.\"Nor is the answer to opt for someone who is completely untested, has no experience and, it would appear, no real message other than one of being the \'new kid on the block\'.\"The fourth candidate, Margaret Mitchell, has stressed her commitment to Unionism and her opposition to new Holyrood tax powers.Party members will rank candidates in order of preference, with votes redistributed if there is no clear winner from the first count.
