Which are all welcome and positive signs for the Democrats. However the Democrats need to not view 2018 as a barometer for 2020.... and assume the results in these states will lean their way. Mid-term elections when you are the minority party with their associated gains are very different than presidential election years - if the Democrats are magically assuming that the popular vote in these states will look like 2018 rather than 2016 then they have another surprise heading their way. The Democrats needs to put forward a reasonable presidential candidate focused on a platform of issues which most matter to the voters. A failure to do this will simply lead to four more years of Trump -- at which point the Democrats can only blame themselves ("We are the party that sucks so bad that we lost to Donald effing Trump not once but twice".)
Most of the 2020 Democrats beat Trump in 2020. Many mid terms you can not assume will repeat in the presidential election but 2020 was no ordinary mid term,it was the biggest win by votes ever and 2018 house dems nearly matched Trumps vote total,which has never happend before.
IMO you are sadly mistaken. Trump will make mince-meat out of most to the current Democrats running for office. The Democrats need to put forward a candidate who has some possibility of winning the office. The Democratic performance in the 2018 mid-term house election was just average on a historical perspective. The Democratic 2018 performance in the 2018 Senate elections can only be considered a failure as they lost seats. I know you and other liberal will attempt to spin 2018 as a great Democratic success -- it was not. Basically it was barely an average mid-term performance. The increasing total number of votes in an election cycle as the total number of citizens increases is basically meaningless. You might as well attempt to compare the popular vote totals in election of 2018 to the 1804 election.
Trump will get slaughtered by most of the democrats running. 2018 was far from average in either race.Dems the the house by the most votes ever and nearly matched the number of votes Trump received,which has never happened before. In the Senate Democrats won 22 Senate races,republicans won 11 Democrats got 53 million Senate votes,republicans got 35 million. Democrats won the Senate races in Pennsylvania,Wisconsin,Michigan,Nevada,Virginia ,Minnesota ,Arizona and Ohio in2018,the states that will decide 2020. Dems won all of the blue senate seat races. Democrats won 8 of the 9 swing state senate seats and only lost the 9th by 20,000 votes Democrats won red states West Virginia,Montana and Arizona and came within 2.5 points in Texas,a seat that republicans won by 25 and 16 points in the prior 2 elections. Republicans lost all blue state races,8 out of 9 swing state races and 3 red state races andonly won thier biggest EC state by 2.5 points
Yet with the increasing number of citizens Trump got fewer votes than Obama in 08,Obama in 2012 and Hillary in 2016.
Remember how all the Democrats in 2016 thought Hillary was the shoe-in. Don't get caught drinking your kool-aid again in 2020.
Low enthusiasm,low turn out in 2016. Dems have shown in 2017 and 2018 that that is no longer the case.
The electorate in 2020 will be significantly different than it was in 2016. The equivalent of a couple of midsized states has migrated here, most illegally. A lot of them will vote. The democrats are one step from getting one of their nutcase judges to rule that illegals have a constitutional right to vote. Pelosi is already arguing they should vote. NC has had a massive influx of millenials and illegals. Cary is full of Hispanics, don't tell me it isn't because I have seen them. Beyond the demographic shift, NC's senators have been among the worst sellouts in the entire caucus. Both are open borders, amnesty zealots. They have no coattails to help Trump. Couple that with Trump's embarrassing failure to get a handle on immigration, and you will get decreased base turnout.
