The dailycaller and youtube are shitty sources. I don't waste time on those. The Sharyl Attkisson site is far less damning than you seem to believe: "“Looks like they were inappropriately offering to pay for his wife,” Lerner said. “Perhaps we should refer to Exam?”" Someone asks a question about whether something needs further attention. Do you think the IRS has a magical way of divining everything without any investigation? Furthermore, there was no investigation, as someone else chimed in that the pay was "not prohibited on its face." So what we have here is someone asking around whether something is an issue, someone else provides information that it isn't, and the issue is dropped.
If anything, that article reinforces the idea that this is a total tempest in a teapot: the IRS actually didn't do something, but Republicans are trying to sound like Grassley was investigated by the IRS. There wasn't even an investigation - there was an email discussion about whether something was appropriate or not.
So when you say "she targeted a senator", you're completely misrepresenting the article - she actually didn't target the senator. As a matter of fact, if she thought that paying for Grassley's wife would be inappropriate, it would have been illegal for her NOT to investigate the senator, just because he is a senator with an (R).
Again, you're really not helping your cause here, and are just making it sound like the birth certificate all over again.
