A. That could help him grab some conservative support
Unless Bush's 37% approval rating somehow turns into a 60%+ approval rating by 2008, photos/videos of the Republican candidate embracing George W. Bush are going to do far more harm than good to the aformentioned candidate.
Reagan was 69, not 72 like McCain will be in November 2008, when he was first elected. Once you get over the 70 mark, age can be a big issue as was proven during the '96 Dole campaign and even early on in the '84 Reagan campaign.
Many women were attracted to Bubba. I agree that Kerry isn't the most handsome candidate on the planet (He was run-down by the end of the '04 campaign too), but have you seen pictures of McCain lately? His age is
really showing. I can only imagine what he'll look like three more years from now.
Rightly or wrongly, people are going to use the torture stories to question whether or not he is mentally fit for the office of presidency. Look at what Bush/Rove did to him in early 2000.
