If I get one more email asking me for money to stop the Republicans from impeaching Obama, I may have to change my email address. And if I were a Republican, I'd probably feel the same way about an endless stream of emails asking for money to stop Obama from exercising dictatorial powers, to sue him, or possibly impeach him.
The GOP knows that crying, "Obama is cavalierly using his executive power to bypass Congress and legislate from the Oval Office!" will trigger a powerful public backlash and reinforce its usual charge against him of dictatorial abuse. It has played this card with maximum skill in its fierce fight to wrest back control of the Senate.
