Explanation for the French.
Hillary was colluding with Russia, so Trump went after evidence of this crime. Dems got scared because if you unravel one thread, they all fall apart.
SO.... they accused Trump of collusion with manufactured evidence.
Trump finds out that Biden was offering moeny (quid pro quo) to Ukraine for favors. SO.. Trump looks for evidence of this.
Dems again get scared because this is another thread in their 10 year long tapestry, and they don't want it to unravel.
SO... the Dems accuse Trump of exactly what Biden was doing.
Any assumptions that Trump NEEDS help to win the 2020 election are pure fantasy. Anyone that has watched the Democratic debates, already knows Trump will win in 2020.
The Dems know this too and they are frantic. They will do ANYTHING they can to prevent Trump from winning in 2020.

Just another case of the same crap the Dems have been pulling since 2016.
