Karl Rove questions Sarah Palin's suitability for president Karl Rove, the former senior adviser to George W Bush, has cast doubt on Sarah Palinâs viability as a White House candidate, questioning if the American people thought she had the âgravitasâ for the âmost demanding job in the worldâ. Expressing the strongest public reservations about the conservative star made by any senior Republican figure, Mr Rove said it was unlikely that voters would regard someone starring in a reality show as presidential material. In two weeks, the former governor of Alaska launches a cable television series exploring her home stateâs wilderness. âWith all due candour, appearing on your own reality show on the Discovery Channel, I am not certain how that fits in the American calculus of 'that helps me see you in the Oval Officeâ,â Mr Rove told The Daily Telegraph in an interview. He added that the promotional clip for Sarah Palinâs Alaska could be especially detrimental to any political campaign. It features the mother of five in the great outdoors saying: âI would rather be doing this than in some stuffy old political office.â Mr Rove, who remains a major force on the US political scene, also implied that Mrs Palin lacked the stomach for the rigours of a presidential primary campaign, which will begin early next year before the first polls in 2012. Mr Rove was asked if the 46-year-old Mrs Palin, who is among the front-runners for the next Republican nomination, would be a wise choice if the party wanted to seize the White House from President Barack Obama. He replied: âYou can make a plausible case for any of them on paper, but it is not going to be paper in 2011. Itâs going to be blood, itâs going to be sweat and tears and itâs going to be hard effort.â He said Mrs Palin had done a âterrific jobâ in 2008 when Senator John McCain took her from near obscurity to the vice-presidential nomination, but added: âBeing the vice-presidential nominee on the ticket is different from saying 'I want to be the person at the top of the ticketâ. âThere are high standards that the American people have for it [the presidency] and they require a certain level of gravitas, and they want to look at the candidate and say 'that candidate is doing things that gives me confidence that they are up to the most demanding job in the worldâ.â After losing with Mr McCain in 2008, Mrs Palin resigned as governor to write books, become a television pundit â on the same Fox News network where Mr Rove is an analyst â and an influential supporter of Tea Party-backed Republican candidates in next weekâs mid-term elections. Thanks to her staunch conservative views, Mrs Palin remains a highly divisive figure with high negative ratings. Many Republican strategists think her selection as nominee would almost guarantee Mr Obama a second term. But such is her popularity among the grassroots of the party, few in Washington are prepared to stick their head above the parapet. No major figure in the party has yet to come out in support of Mrs Palin, including Mr McCain, who refused to endorse her yesterday. Mr Roveâs forceful comments signalled his confidence in his own standing and track record as the architect of Mr Bushâs two election victories. Mrs Palin could face further attacks from within the partyâs hierarchy in the coming months as the competition for the nomination heats up. All the indications are that she will run for office. She has delivered a speech in Iowa, where the first caucuses are held, quietly accumulated members of staff and has a sizeable pot of money. But Mr Rove suggested that âoutside of the true believersâ, most Republican primary voters were still watching the race and would choose the candidate most suitable for the role. âThey are going to be saying 'the person who can win is the person who proves to me that they are up to the jobâ,â he said.
