Sounds speculative, but Lois Lerner was targeting the Tea Party specifically to have this effect.

So, the burden should be on the side that disagrees with this thesis to prove their claim.

Did the IRS Tea Party allegations help Obama’s presidency?

For left wing Democrats...

...conservative Americans are the real enemy.

According to new IRS emails obtained through a Freedom of Information Act request from Judicial Watch, former head of tax exempt groups at the IRS Lois Lerner was in contact with the Department of Justice in May 2013 about whether tax exempt groups could be criminally prosecuted for "lying" about political activity.

"I got a call today from Richard Pilger Director Elections Crimes Branch at DOJ ... He wanted to know who at IRS the DOJ folk s [sic] could talk to about Sen. Whitehouse idea at the hearing that DOJ could piece together false statement cases about applicants who "lied" on their 1024s --saying they weren't planning on doing political activity, and then turning around and making large visible political expenditures. DOJ is feeling like it needs to respond, but want to talk to the right folks at IRS to see whether there are impediments from our side and what, if any damage this might do to IRS programs. I told him that sounded like we might need several folks from IRS," Lerner wrote in a May 8, 2013 email to former Nikole C. Flax, who was former-Acting IRS Commissioner Steven T. Miller's chief of staff.

And:

Just a few short days later on May 10, 2013, Lerner admitted and apologized for the inappropriate targeting of conservative tea party groups during an American Bar Association Conference after answering a planted question. Further according to Judicial Watch, "In an email to an aide responding to a request for information from a Washington Post reporter, Lerner admits that she “can’t confirm that there was anyone on the other side of the political spectrum” who had been targeted by the IRS. She then adds that “The one with the names used were only know [sic] because they have been very loud in the press.”

In other words, only conservative groups were being looked at for criminal prosecution.
