Party of Liberty vs. Party of Government
In previous years, Democrats never chased anyone from their party. They fled.
The high tax, anti-business, pro-identity politics and weakness on foreign policy caused many Democrats to flee the party in the 80s. A new generation of moderate Democrats has been born but the party is being run by its liberal wing. The infighting is becoming more pronounced and will get worse in the coming years.
Republicans need to buck up and go back to their core principles of liberty, opportunity, low taxes, a tough defense. Those are pretty good blocks on which to build. In the meantime, Republicans need to oppose the worst excesses of the Democrats. Somebody has to and they're all we got.
