I won't argue that every Republican who refuses to vote for Trump makes it easier to elect Hillary, simply by creating a situation where she requires one fewer vote to gain an overall majority (I know it's not quite that simple with the Electoral College and all that, but if you live in a state that might go either way it could matter if it's that close). That said it's a pretty lame situation if either party believes they can put forward as undesirable a candidate as they choose and their registered voters are somehow obliged to vote for someone they just can't back with a clear conscience.
It's sad that both major parties have put forward candidates who are so very divisive. I rather get the impression there are many voters on both sides who struggle with the candidate their team has thrust upon them, and probably many voters on both sides who will vote for their side's candidate for no reason other than to keep The Other Guy out.
It's like they say in virtually every election -- NOBODY ever finds a candidate that they agree 100% with. If you can find someone that supports 70-80% of our issues, that's probably as good as you're ever going to find it. To refuse to vote for someone because their thinking is not 100% allgned with our own is pretty foolish.
Regarding the "derisive" candidates, it is a matter of perception -- which usually is something created by the leftist mass media. Hillary certainly IS derisive because of her criminal background and the horrific performance she gave as secretary of state and everything else she has done. Even most Dems (most of who will vote for her anyway -- if they show up at the polls) do not like her and there is a pretty good number of them who are switching to Trump.
Her record, itself, disqualifies her from even running for president. But there she is, with the coddling press, getting the nomination after performing in the same manner that makes her so derisive in the first place -- rigging the system so that she automatically got the nomination over Sanders.
As for Trump, he speaks loudly and boldly. And, based mostly on that, the mass media has portrayed him as some sort of monster. But, getting back to the percentage of issues that a candidate might agree with us on, look at the points he is running on....
He is for stopping illegal immigration, which is ruining our economy, increasing our drug problem, paving the way for terrorists to sneak through, etc. He is for supporting our veterans with proper health care through the VA. He is for nominating solid, conservative supreme court justices who will act based on the intentions of our constitution, he is for bringing jobs back to the USA and creating a much stronger economy for the nation. He is in favor of a massive rebuild of our military, which Hillary & Obama have virtually dismantled, etc.
I could go on & on. But I hope you already get my point. There is very little that Trump is running on that would not be highly supported by most sober, patriotic American voters.
And anyone, who actually does support those values, and refuses to vote for Trump simply because he is loud and bold -- is directly responsible for helping elect a socialist/communist loving candidate who OPPOSES all of those values.
In reality, the differences between two candidates for POTUS have probably never been more striking and well defined in our nation's history.
