To me, there is a much more worrisome aspect to Mr. Rove raising this issue. While it is entirely legitimate to discuss, during a political campaign, the candidates' ages and any health issues they may have, to raise this particular issue in this way, and at this time (since the election is over 2 years away) makes Rove and , by association, Republicans, in general, seem petty and stupid! It also makes them appear desperate and, somehow, afraid of a Clinton candidacy. Republicans would be better served to work hard on the 2014 mid-term election of Senators and Representatives this coming November and save worrying about the Democratic Presidential nominee, whomever that is, until the time comes. And, even at that time, make the election about issues and the candidates' records rather than petty BS. Also, I would admonish them not to get too wrapped around the axle about Ms. Clinton unless, and until, she becomes Democrats' nominee.
In this regard, I am reminded that during the Democratic party primaries to select their candidate to run in the 2008 general election, right wing radio and TV personality Sean Hannity shouted from the rooftops encouraging voters to join his "Stop Hillery Express".
Well, Mr. Hannity got his wish and Hillery went down to defeat. So, instead, of Ms. Clinton, what Hannity got was Barack Obama!
HOW'S THAT WORKIN' OUT FOR YOU, SEAN?
