This was planned so it would be on the front page and lead newscasts for a week before the election. All during that time the media would explicitly blame Trump, as they are doing.
1-2 days from now, there will be another manufactured crisis which will rip the bombs off the front page and thus leave people with the idea that Trump is responsible.
After the election we will find out who sent the bombs, but it will be too late.
Riiiiight.
About the same time we find out
what was in Hillary's emails that made NYPD cry
who is actually funding the "caravan"
what is in Zer0's school records
who killed Seth Rich
who killed Lieutenant Quarrel
who hired Craig Livingstone
