According to The Times, the Democrats will seek to portray Palin as too inexperienced a candidate to be just a “heart beat away” from the presidency.

They are trying to ascertain if Palin’s foreign travel was limited to just one trip to Germany and Kuwait last year.

Tom Daschle, the former Democratic Senate leader and a senior aide to Obama, said: “With absolutely no experience, are we ready, if necessary, to place our future in her hands as commander in chief and our premier negotiator with other world leaders?”

Daschle has also questioned Palin’s skepticism about global warming. Then there is also the fact that she might have abused her office when she fired the Alaskan public safety commissioner, Walter Monegan over his refusal to sack Palin’s brother-in-law, a state trooper previously involved in an ugly divorce with Palin’s sister.

Those allegations are now the subject of an Alaskan ethics investigation, the results of which will be published on October 31 - five days before the general election.

Palin also recently told an interviewer that she did not fully understand the role of a vice-president. (ANI)
