To me, the question can and should be divided into two categories. Rush Limbaugh is a wholly distinct category from Glenn Beck.
I cannot take Glenn Beck seriously. He is too much the naughty little boy dropping his britches in the public square to horrify his parents and scandalize the passing crowd. It doesn't mean that he gets his facts wrong, however, and so from that standpoint, I am of two minds about the Peck's Bad Boy of punditry. If he could dial back just a trifle on the outrageous locutions, he might be an effective mainstream pundit.
Rush Limbaugh has been around for what seems like forever. He is and always has been a burr under the saddle of any and all left-wing dopes trying to flimflam the American public into believing the latest load of bullshit being peddled by the great and [temporarily] powerful! Rush is Rahm Emanuel's worst nightmare and I'm sure it must be frustrating as hell to President Obama's nasty butt boy that he can't just wave his magic wand and wish Rush out of existence. Note to Rahm: Better men than you have tried, bucko, and have failed miserably! I don't always agree with Rush Limbaugh but I always love him and I always respect his intelligence and credentials as a conservative pundit. Demonizing him, as the White House is attempting to do, only makes him stronger.
All this White House posturing vis-a-vis Glenn Beck, Rush Limbaugh and Fox News is by no means anything other than a miserably pathetic attempt to distract the American public (the right leaning portion of it anyway) from the fact that the Obama administration is attempting to frog march us into outright socialism at an astonishing clip! And no, neither Rush nor Glenn Beck pose any serious impediment to the Republicans recapturing a plethora of House and Senate seats in 2010. The case in favor of that happy prospect is being made quite capably by the White House and the current administration.
I am a conservative Republican woman; have been one all my life and am not in the least ashamed of my political stance. My question to anyone who is not a conservative is, why in hell not? What's wrong with your critical thinking apparatus? Are you daft?
