Not exactly.  I assume you're familiar with the fable of 
The Boy Who Cried Wolf.   That's why Republicans are frustrated.  They have no credibility  outside the nutter bubble.  They've spent the last seven years  scurrilously attacking anyone and everyone associated with the Obama  administration.  In most cases, these attacks have been based on lies.   Even when there was some kernel of truth within an attack it was buried  under the lies intended to turn a small problem into a MAJOR SCANDAL!!!
Even when such lies have been soundly refuted, the GOP faithful continue  to parrot them (e.g., Obama's a Muslim, Obama was born in Kenya, etc.)   They love their lies.  There's a whole industry built around  deliberately lying to the GOP faithful.  Just like a battered wife, the  faithful keep coming back for more, no matter how blatant the lies.  The  result?  Those outside the nutter bubble see the GOP faithful as  ignorant rubes, stupid, simple people who can't tell truth from fiction.   They therefore have no credibility.  Their accusations against Clinton  are presumed to be just more of the same raging BS they've been pushing  for years.
In short, the GOP are the boys who cry wolf.  Even if they happen to  tell the truth, they are assumed to be lying yet again.
