It shows who has a bigger war chest comming into the midterm elections that's only 15 months away.
At this point, the Republicans keeping control of the Senate is all but guaranteed. It's only a matter of how many more Senate seats they will pick up.
One also has to keep in mind, the NRA spent over 30 million dollars to help secure Trump's Presidency. The NRA will also be extremely helpful in maintaining Republican majorities.
Let's also not forget the impending "Awan Bros." scandal that's going to break any day now. The Awan Brothers have been the IT staff to over 80 Democrat Congressional offices. If the Awan Brothers activities become known to the public, this scandal will be like bone cancer to the DNC.
I personally predict that Democratic party leadership will be shaken up after the results of the 2018 election turn out poorly for them.
