Arguably let it happen in 2008 as well. Two or three states look suspicious, but sadly Obama was probably the lesser of two Big Evils compared to NoName (despite Palin VP a likely Patriot sleeper). 2012 clearly rigged, but military intel was probably on defense after being targeted by Obama. Romney might have been Patriot sleeper (flipped) with Ryan VP placed as Deep State safety. Real Biden VP likely got leveraged (and later replaced with body double ~2014-15) to assist as a "mole" within Obama whitehouse, and Obama knew it. [per Biden, 40 years of known treason is easy to leverage].

Deep State likely forced to pivot to Obama in 2008 after Palin placed as VP. Likely plan was to impeach/remove NoName and install Patriot sleeper Palin with new VP Trump. Patriot "backup" was a leveraged Biden, but Deep State given the choice. Biden Patriot leverage done post 2012 election to prevent swapout of Biden by Obama? Military may have threatened to remove Obama in 2012, thus shadow war that broke out.
