Go to page 22 to answer you question if Obama spied on Romney during their election.

Sadly it only leads to another mystery, as to what exactly is “Report regarding Technical Surveillance Counter Measures inspection dated July 19, 2012” and what precisely it says.

think Romney was eavesdropped on during 2012? see page 22

This is a 40 page PDF: obviously too big to post here.
Conclusions from the article:
Conclusions
Historically, incumbent Presidents order espionage (to include eavesdropping) against the candidate of the party that opposes them.
This election linked espionage may include illegal eavesdropping from one political party against the other party, or it may involve espionage inside the respective parties.
Historically, the NSA has been used for this sort of eavesdropping, but other agencies may be involved as well.
It would have been astoundingly unusual for President Obama not to order the eavesdropping of Candidate Trump, or Candidate Sanders.
The NSA has a partnership agreement with the intelligence services of four other nations, to include the British GCHQ through the Five Eyes partnership.6)By performing a “Reach Around” the NSA can provide GCHQ with access to the private communications of a Presidential candidate, so that GCHQ writes up the information contained in the intercept, which GCHQ then leaks through various deniable sources to the media in order to control U.S. elections.
President Trump has a legitimate claim that the NSA eavesdropped on him during the Presidential campaign of 2016.
President Trump has a legitimate claim that the NSA routed signals out of Trump Tower to GCHQ, who were an integral mechanism to attempt to manipulate the U.S. Elections.
President Trump claims that President Obama had his wires tapped are legitimate, credible, and viable.
It is highly probable that President Obama did in fact violated the Fourth Amendment and attempted to sabotage the Presidential Campaign of Donald Trump by using the NSA and its various eavesdropping programs.
