Anyone who thought the fight against evil is won or lost in a single election is naive in the extreme.
These are generational issues and fights. The fact is the country is still polarized even after this election. Iran issue might be over forever after this, but the domestic issues remain.
If you are going to battle with the GOP/RNC, you are doing so with both hands tied behind your back. The GOP has been an ineffective party for decades, which can't be accidental. Their outreach to pretty much any group/demographic is pathetic, and there seems to be no discernable message coming from anyone other than Trump (and that didn't go well this time around). The Bush wing of the party will now try to take back control of the party, which will be a complete disaster if they succeed in those efforts - nobody likes those people. Politics is always a "fight", but the landscape changed drastically yesterday as we move forward with an even weaker GOP.
