With November 4th being right around the corner, shouldn't each candidate be using everything they have to help win voters over?

My most recent post gave a clear depiction of Barack Obama's views concerning gun control and the Second Amendment, which calls for individuals to have the right to bear arms.  However, I find it extremely interesting that there has not been large amounts of information from this issue coming from John McCain's side of the spectrum.  In my opinion, there are clearly issues that each candidate can highlight or call attention to in order to show that they would make the best president.  Gun control is an issue that we would typically see the Repbulican candidate emphasizing in his political interviews and debates; but, this has not been the case with John McCain recently.  I have been putting lots of time into researching this issue and recently all I have been able to find are clips and interviews where Obama is addressing gun control rights.  Now, it is probable that Obama would be addressing this issue heavily knowing that it would be an issue that he may potentially loose some voters on, but I still think McCain should be addressing this topic more evidently.  We clearly know Sarah Palin's view concerning gun control and she presents her argument clearly, but why has there not been any recent ads or campaigning revolving around this issue?  McCain may feel that the issues he needs to be concerned with mostly are not those in which American people can automatically assume his stance towards gun control, due to earlier interviews, but I still believe McCain should be emphasizing his opinion concerning this issue more clearly.
