If the 2020 US Presidential and Senate Election is to be similar to the 2016.

[nkpolitics1212]

States voted state political party line for US Presidential and US Senate Election.
The 2020 Democratic US Presidential Nominee should try to win AZ and NC in addition to the Clinton 2016 States plus MI,PA,and WI. Winning AZ and NC will help the 2020 Democratic US Senate nominee in AZ(Mark Kelly-D) and NC(Jeff Jackson-D) get elected. The Democratic 2020 US Senate nominee in CO(Mike Johnston,Kerry Donovan or Joe Neguse-D) and ME(Hannah Pingree-D or Jared Golden-D) will win due to the 2020 Democratic US Presidential Nominee's coattails.

Democrats win every Democratic held US Senate seat up in 2020 except AL(Jones-D). Democrats win Republican held seats in AZ(McSally-R loses to Kelly-D), CO(Gardner-R loses to the likely Democratic nominee-D), ME(Collins-R loses to the likely Democratic nominee-D) and NC(Tillis-R loses to the likely Democratic nominee-D).

1. we need good senate candidates in every state

so that our nominee might ride their coat tails.

it is entirely too early to be making predictions in an election this close.
