Interesting to note that Trump is now turning on his own political party. I've often heard the phrase, "we hurt the one's we love the most." Yes, domestic disputes can be bad. Trump has been an artist at this as, not that long ago, he said that Putin is a more effective leader than our own President Obama. Yes, the one's closer to us are the one's we tend to trash.
Many types of folks do this. For instance there's "black on black violence." Republicans have been prolific at this recently, however. After the tragedy in Benghazi, when the US ambassador and others were assassinated, much of the criticism has been focused on the supposed miss dealings of Hillary Clinton, in response to this tragedy, rather than the true culprits who were the terrorists. No one of course, not even Hillary Clinton, should be above scrutiny, but it does seem like Americans turn on Americans quite easily.
Similar things happen in romantic relationships. Seems like relationships are often a war zone. It must be a form of human nature to most likely hurt those that are in close proximity.
Some speculation about what might happen if Trump were to step aside.
He has no plans to do this, but sometimes people dig in deep and then suddenly announce the reverse. Years ago, I remember when Senator Bob Dole's presidential run looked like it was going on the rocks during the primary, reporters ask him the obvious question. He replied, "we're staying in, we're staying in." Seems like it wasn't long after that, he left the race. Of course that was still during the primaries, not the final election.
I hope Trump stays in as he does seem to be bad for the Republican brand. If he were to step aside, however, my guess is that Pence would be put forward as the Republican presidential candidate. Pence wouldn't be very good either, in terms of policy (my opinion), but his less volatile style would be seen as a safer bet. Republicans would see him as a way to try and unify that party because he's still part of the Trump ticket, but also more palatable to what is termed as the "Republican Establishment."
With Trump on the ticket, we (folks who lean toward the Democrats) can hope he looses, of course and also hope he can bring down many of the Republican's in Congress. Maybe the Senate will go back to the Democrats, or even both the House and the Senate.
Imagine Democrats controlling both Congress and the Presidency, but it has happened before and it didn't bring us to Nirvana.
I don't anticipate any politicians to be our total saviors, but it would be nice to see some gains made by the Democrats.
