One really big concern possibly the biggest has to be "What kind of extra-constitutional (if not flatly unconstitutional) actions will President Obama take after the election and before the new Congress is sworn in?" Highly likely, especially since it has been promised repeatedly, is an executive amnesty to "legalize" the illegal aliens living here.
Of course, we're also now aware that President Obama has delayed the release of information on next year's large Obamacare premium increases till after the election, too. We also learned in the last week or so that the Health and Human Services Department (HHS) and the Centers for Disease Control (CDC) diverted appropriations from development contracts for Ebola vaccines to contracts for unrelated things placed with Democrats' political friends. Was that corruption? Maybe, but based on other things we're seeing, it may have been simple incompetence.
Of longer-term concern are recently released figures showing where our government's budget dollars are going. It's notable that almost two-thirds go to income transfers money taken from taxpayers who produce and given to non-taxpayers who don't. And that's the part of the budget that's exploding. Only about 6% of the budgeted money is spent on actually governing.
And then there's the issue of Weapons of Mass Destruction (WMDs). We were told for a decade that no WMDs were found in Iraq. The New York Times and every Lefty in the country endlessly repeated the Democrats' mantra: "Bush Lied, People Died" or sometimes "Bush Lied, Thousands Died". (In making these statements, they all ignored the fact that Saddam Hussein's Iraqi government used chemical weapons against Iraqi minorities and in the Iran-Iraq War.) Now, the New York Times has apparently, and belatedly, discovered that lots of WMDs specifically, chemical weapons were found all along. And they were found all over the place, not just in one location. Here's the map and notations from the New York Times article.
Perhaps the New York Times decided to make these admissions because some of the bases with stockpiles of chemical weapons have now been taken over by the so-called "Islamic State" in Iraq, as Bashar al-Assad's equivalents have been in Syria. These weapons have been banned by every civilized country on the planet, but ISIS has already been happily using them against their enemies as did both Saddam Hussein (Iraq) and Hafez al-Assad (Syria) before them, and probably Bashar al-Assad more recently.
So how do we tell the difference between the "moderate muslims" and "peaceful muslims" on the one hand, and the uncivilized barbarians like ISIS on the other? I don't know of a way to make that distinction. Indeed, there may not be a way. I come to that conclusion because it appears the muslims can't determine who is peaceful and who is not, either. In fact, anyone (particularly any imam) who speaks out for moderate positions and against the barbarians is very soon killed. I suspect that's the reason for this:
Because you never know when some muslim barbarian will take offense to something you said or to something you did or to your existence, and decides to do something about it.
