to Darrell Issa. Unfortunately it won't help much. It is important to understand WHY these 'scandals' have come up and will continue to come up. You need consider the audience these scandals are intended to reach. The average republican, I'd go as far as to say most republicans, believe some combination of what they are told to believe and what they WANT to believe.
Obama's presidential eligibility is a good case. After postings from local papers, local interviews and proof of a birth certificate, a large number still believe that Obama is a Muslim born in Kenya. Interestedly Canadian born Ted Cruz has no such difficulty...
Republicans do not see a problem with this logic. That 'scandal' has done it's job.
Another example is how Obama used the IRS to target the Tea Party. Surely no proof of that, still another 'scandal' has done it's job.
Suddenly, Obama has....
used the IRS to target the Fox News.
used the IRS to target the prayer groups.
Used the IRS to target Billy Graham Ministry and Other Christian Groups.
Naturally if Obama had not misused the power of his office Mitt Romney would have been elected.
It makes no difference if these scandals have a grain of truth or no truth at all. Any response will have little or no effect.
Remember the mindset of the intended audience.
Remember some wise words Paul Simon wrote long ago.
"A man hears what he wants to hear and disregards the rest"
