Other than hate trump the democratic party doesn't have a message.
THey are completely disorganized.
Trump has a 50% approval rating on the economy.
he has a 43.1% approval rating overall.
You can't mount a challenge or just moral outrage.
It is not sustaining.
That right now is the main problem with the democrats.
I see a split congress like with obama.
Republican house democrat senate etc ...
I agree, too a point.
Where I agree, is in the Dems not having a message.
Where I disagree, is in the specific application. Midterms are low volume events highly dependent upon base turn-out. I'd argue that fear & anger are good motivators for this type of low volume base-dependent elections.
In further support of anger being a positive force in driving the electorate, I'd argue that anger over Washington Status Quo is in large part what brought Trump to the Presidency itself - and that was a Presidential election! Now, it's the Dems that are angry & shut-out. In a mid-term.
However as to the 2020 Presidential election, you are right: the Dems need a message. But for the midterms, I suspect anger motivating the base may indeed carry the day.
One more item as to why I believe the Dems may prevail in gaining the House in November. The Generic Congressional Ballot has floated back up to a 8-9 pt Dem advantage, after having earlier in the year collapsed to 3-1/2. But more importantly, the Dems seem to be enjoying a wide (voting) enthusiasm gap to their advantage. I have not seen a recent enthusiasm poll that shows the Dems less than double digits above the GOP, and some polls are pushing near 20 pts in differential. If accurate, this is huge. Really huge. It historically has been the Repubs having a solid enthusiasm lead in midterms, never less than a solid 7-8 pts or more, so something has definitely shifted in this specific election cycle.
Due to the GOP positive effects of gerrymandering, lay of the land, and voter suppression, I was calling this election as the Dems being only slightly likely to take the House, or if not come close to it. I'm still sticking to this call as the Dem minimum performance, but now due to the numbers I presented in the paragraph above, I'm leaving open the possibility of a significant Blue Wave (maybe 35-40 seats or more). I'm not outright predicting a wave, but I will not be at all surprised if one occurs. And I now think a wave is more likely than it was several months ago.
