The This Week Roundtable discussed what McCain needs to consider, not the least of which is age, when choosing his running mate:

George Will makes an excellent point. We've already seen how the Democrats are going to tie McCain to the administration, and choosing someone like Rice -- or anyone in the Cabinet -- would only hurt McCain's efforts to blunt those attacks. Moreover, whether we're talking about Rice or any other potential minority pick, Republicans aren't going to win the identity-politics game against Democrats. That's not to say Republicans should avoid a minority choice -- they should pick whomever best serves McCain's chances -- but using race and/or gender as a prerequisite could lead them to pick someone, like Rice, who has never experienced the rigors of a campaign.
