The good news in the most recent primary elections is that the strong Republicans on the one hand, and the anti-Clinton/Obama theme of Bernie Sanders on the other, soundly thrashed their opponents (in the cases of Trump and Cruz in the Republican race) or have mightily frightened the opposing contender (in the case of Bernie Sanders on the Democrat side). It now appears that conservative ideas and ideals will be represented in the Republican Party in 2016 (to the chagrin of the old establishment Republicans) and that leftist/socialist ideas will carry the day for the Democrats.
So one can truly say that each party is unifying its base, but the party unification now creates two very different cliffs with a wide canyon between them at the national level. There will still be moderates on both sides that will interact with the dedicated conservatives and liberals in the respective parties, but the general drift of the two parties is to put more ground between them and have less cooperation and overlap in their policies.
Back in the 1950s and 1960s it was said that America was a peaceful, happy democracy because most people did not vote at all since the two parties shared so many ideas and principles of how government should be run that citizens felt they didn’t need to vote in order to remain free and prosperous. But this idea is no longer true and many people now fear losing the liberties and wealth they had ten years ago.
Bernie’s Democrats want more government handouts and goodies regardless of what the constitution says and regardless of what the cost is, and conservatives want much less government involvement and control in their lives. The divide could not be more clear, nor more threatening to our nation.
