It's the conservative media, ranging from The Wall Street Journal to the Drudge Report, which have been creating the Great Overexposed Hillary Clinton. Here is an example of the WSJ "examining" her record as Secretary of State (sub. req.)
The effort is brilliant Machiavellianism. This politico hasn't even declared herself as a candidate for president for 2016. And Americans still have to get through the 2014 elections, with all the upsets those can trigger.
Yet, she is being overexposed in the influential conservative media. Some of us who have been supportive of her over the years are coming to long for a fresh face. Female or male. And, yes, putting her under such an intense microscope has given prominence to every wrinkle. The woman looks, yes, old.
A fresh face could steal the show. Democrats and independents like myself could get out our pom-poms and cheer the new presence in the presidential race.
The newbie on the scene would have to avoid peaking in the media too fast. If that performance art, including considerable restraint, is done right that player could become president. Hillary would be done.
