Politics is enough to give anyone a flare up. Ann Romney may not be physically strong enough to be first lady. Politics continues on during the presidency. She might not have to put up with racial commentary/attacks for four years like Michelle Obama, but Mitt will be faced with life and death decisions every single day. There will be politics every single day. Perhaps the democrats will collude to block Mitt's agenda on Day One. Perhaps Mitt will start a war, and then the whole country will be stressed, with people facing their own individual flare ups and without healthcare because Mitt and the republican Congress would have repealed it. The stress would be enormous.
If you missed the video of Ann telling us that Mitt is "golden" and that they will not release any more tax returns, you can watch here.
