Wouldn't the request for affadavits mean that she's going to court?

Candidates can't request a recount, they can only go to court to appeal the decision of canvassing boards. In that case, the court may or may not order a recount.

Voters can request a state-wide recount, but it has to be done by each district/precinct, with 3 voters from each swearing an affidavit that an error has been committed.

Or they have to swear that an error may have been committed? I personally couldn't swear that I know for a fact that an error has been committed, only that I have suspicions.

There are two ways for voters to initiate, each requiring a petition with three signatures from each district/precinct.

One way is to petition with the county, and that requires an affidavit saying that an error has occurred.

The other is to the court of common pleas for a recount for paper ballots, or a recanvass for electronic machines. and there doesn't have to be a claim of error/fraud.

Voters may initiate recounts with the county boards with a “petition of three voters of any district, verified by affidavit, that an error, although not apparent on the face of the returns, has been committed….” The county board shall then “conduct a recount or recanvass of all ballots cast.”  See 25 P.S. 3154(e).

Voters may also initiate recounts in the court of common pleas  under 25 P.S. 3261, which governs  recounts requested in counties using paper ballots or they may initiate a recanvass under 25 P.S. 3262, which governs  counties using voting machines (DREs).  In the counties using paper ballots and in those using voting machines, voters may petition for a recount in any general, municipal, special or primary election, for either an office or a question.   These recount requests must be accompanied by the signatures of at least three voters per precinct or election district. See 25 P.S. 3261(a) and 3262(a).  Unless the recount initiators are alleging a particular act of fraud or error and offer evidence supporting the allegation, then the  recount “shall include all election districts in which ballots were cast for the office in question” and that the initiators' petition “must be filed in each election district.” See 25 P.S. 3263(a)(1).

So I guess we'll find out what route they're going to try.
