Recent polls by the major networks and the Associated Press have shown the public is uncertain about Republican vice presidential candidate Sarah Palin’s ability to lead the country if she was to be thrust into the presidency.

The Alaska governor has also come under fire for a comment in a recent interview that the a role for the vice president is to be “in charge of the Senate.”

Adding to Palin’s mounting criticism is some $21,000 in commercial airline expenses for her children to events they were not invited to attend. Palin’s office has defended those expenses, citing “an expectation that the First Family participates in community activities.”

On the Democratic side, concern over Joe Biden being a loose cannon on the fly based on various comments he’s made causes concern for some voters.

He has also come under fire for his positions, prior to being selected as Sen. Barack Obama’s running mate, about Obama’s readiness to be president.

So what does it all mean?

Not much.

When voters go to the polls on Nov. 4, they will do what voters always do when choosing between national tickets. They will choose between the men who lead them.

That’s because no matter how much scrutiny is given to the vice presidential candidates, voters understand they are voting primarily for a president. Certainly, the qualifications of the vice presidential candidates must be taken into consideration because they are a half-step from the Oval Office.

But at the end of the day, voters will choose between Obama and Sen. John McCain because they know those men are the ones who will have the responsibility of the highest office in the land.

So despite all the criticism and scrutiny Palin and Biden have received, and will continue to receive, from their critics, history shows that voters will choose a ticket based primarily on who leads it.
