First off:
1. Hillary didn't install the servers. The were installed for Bill when he left office, as part of his communications system with the incoming administration, and for use in their Foundation work.
Because past Presidents are given briefings and sensitive documents, the Clinton servers were set up with the best anti-hacker protections money could buy, and the Clinton servers were never hacked - despite multiple attempts. The same cannot be said for government servers, which are installed on a lowest bid contract basis.
2. Clinton asked the outgoing administration how they handled email given the 25 megabyte restriction on storage for all government employees. The Bush Administration told her they used private servers and recommended that Clinton do the same.
3. The servers were not illegal until 2013. Here's an article on the Bush Administration losing 22 million emails, and crickets from you clowns.
The Democrats released a new email exchange between the two from 2009.

This is from a 2015 article:
"Clinton’s private email account surfaced publicly in March 2013 after a convicted Romanian hacker known as Guccifer published emails stolen from former White House adviser Sidney Blumenthal. The Internet domain was registered around the time of her secretary of state nomination."
and this one:
"President Barack Obama signed a bill last year that bans the use of private email accounts by government officials unless they retain copies of messages in their official account or forward copies to their government accounts within 20 days.
The bill did not become law until more than one year after Clinton left the State Department."
The computer server that transmitted and received Hillary Rodham Clinton's emails -- on a private account she used exclusively for official business when she was secretary of state -- traced back to an Internet service registered to her family's home in Chappaqua, New York, according to Internet...

3. Clinton ordered her staff to go through the server, delete all personal emails and emails relating to Chelsea's wedding, and ensure copies of all SoS emails were sent to the Archives. And then scrub the servers. There is nothing illegal or nefarious about that.
There was no attempt to circumvent the law. The order was issued, in writing, 3 months before the House sent a subpoena for the server and the emails, and after 6 Benghazi Investigation had found no evidence of wrong doing. You keep telling us that Hillary's email was secret and hidden, and absolutely none of that was true.
Everybody in Washington knew she was using her private email because her email address was on every email anybody in the government sent to HC, or from HC. Top Republicans knew she was using a private server because they told her to do it.
What does it take for you to realize that the email investigation was a bogus allegation, meant to discredit Clinton's run for the White House.
Republicans, having succeeded in keeping Clinton out of the White House with a phony investigation of the Clintons, are trying to run the same playbook on the Bidens. The American people won't get fooled again.
