Trump took to Twitter to target Obama as he believes that Obama used his powers to target his incoming officials, and he also targeted Obama because Flynn has now been acquitted of all the charges.....
You are correct as to the timing of his comments about Obama. But as for why he "targeted Obama" it's not because of Flynn issues.
It's simply because evidence implicating Obama has arose.
Isn't that right?
Democrats now need to bring in an unknown person with no laundry list of skeletons in the closet. Then let Biden quietly disappear. Then they'll enter the election cycle with what they think is a Big Surprise, and two weeks before the final day come out with their usual Big Shocking Lie about Trump.
But for this Mystery Candidate to have a goat hair of a chance it's got to be mainstream Americana, none of this radical communist progressive nonsense like we saw with all the Democratic primary candidates. That's why Biden got in easily, right? I don't think the fat old men in the Den power structure back room are smart enough to pull this off, though.
They'll lose anyway, so does it matter?
