The tracking average of polls that I've been using is from RealClearPolitics. I like the readability.
Perhaps the best post of all of these: Avik Roy, a conservative with a focus on medical policy, talks about how the GOP and conservatives have become a cloak for white nationalism. The leadership of the party winked at concerns about racism and lack of appeal to minorities, so they didn't see the extent to which it was happening... until this year. My prediction is that the GOP has at least another 4 years of chaos ahead before there is any semblance of unity.
At National Review, there is a long but fast-paced article about the problems with conservative media. The overwhelming problem is that non-conservatives don't get their news and don't trust conservative sources. Then the author inadvertently show why people shouldn't trust conservative media source when he talks about coverage of economics. He used a purely statistical argument to conclude Obama has done worse with the economy, ignoring the context that Obama inherited the biggest financial crisis since the Great Depression. By the same author, conservative media personalities enrich themselves and conservative media is a hive of charlatans. Conversely, the liberal media has been crying 'wolf' for years before they got someone like Trump who is actually terrifying.
We can't leave the topic of conservative media without some schadenfreude at the infighting between various conservative media outlets over whether Trump is great or an abomination.
All politicians tend to ignore issues that show their weakness. According to Kilgore, terrorism is a weakness among Dems. I agree. It's a serious issue that any government in power needs to deal with. Don't stand there pretending that there aren't dangers because that's denialism.
Trump calling for his supporters to monitor polling places is not only scary, it may be illegal.
A list of Trump's threats and insults. Another list suggesting 33 actions/statements that Trump might regret if he ever decides to get specific about what he might have said that he regrets.
Finally, a completely different sensibility in the analysis/theory that Clinton is trying to reach out to GOPers instead of tarring them as disgusting Trumpettes.
Update 9/1/16. More on conservative media, seconding what was already written, but maybe a few good points besides. By Bill Kristol's choice for president.
