She was active and visible in her husband's second presidential campaign during 2007 and 2008, despite not wanting her husband to run initially due to bad memories of their 2000 experience and worries the effect on her children, especially son Jimmy who was headed to serve in the Iraq War. She eventually supported her husband in his goals, but defined her own campaign roles; she frequently returned to Arizona to attend to domestic duties or interrupted campaigning for her overseas charitable work. She preferred to travel with her husband and introduce him rather than act as a campaign surrogate with a separate schedule. She wore her hair in a fashionable but severe style and was sometimes seen with an unsmiling countenance in her appearances. In August 2008, a member of the public shook her hand very vigorously, aggravating her existing carpal tunnel syndrome condition and causing her to slightly sprain her wrist. The campaign exacerbated her migraine headaches and she sometimes had to wear dark glasses to shield herself from bright lights. The pressures of the campaign also brought out a range of behaviors between her and her husband, varying from moments of great tenderness and concern to raging arguments that dismayed their staffs.
