If you click on the link in the OP, the article points to a continuous slide in active-duty support over the last two years. If the trend in the graph continues (at the same rate), then trump will be underwater before the/his next election, which will be HUGE ...
The graph with an unnecessarily truncated y-axis and meaningless decimal points does not help your case. Why are you posting it?
Even this dfference is on the edge of significance at best, and the article repeatedly points to meaningless differences as if their direction were important. Not much to be proud about in this observation, I'm afraid.
But it is in a critical zone. President Trump cannot expect the military to do his political dirty work on his behalf. He is leaving the range in which he can count on the soldier vote to rescue him politically.
It also suggests that the President has little leeway for any War for Profit -- let us say taking over Cuba or Venezuela on behalf of American corporate interests. Trump behavior is getting erratic. The military culture may like the chest-pounding nationalism of Trump more than the subdued nationalism of Barack Obama, and likes the provision of more materiel to the Armed Forces.
Still, who wants to die for Big Oil, big banks, or agribusiness corporations?
Not really. Adjusted to inflation the DoD gets about what its been getting under Obama. In fact before Obama had to play chicken with the House "Freedom" Caucus, is trifecta spent more on the military in gross dollars than Trump's trifecta.
Its funny how many rightwing military vets and personnel repeated rightwing talking points about the debt and deficit when Obama was in power and now Trump is president they dont give a sh**t anymore. Meanwhile the Iraq War costed the US, trillions. Directly contributing tk the debt and deficit along with other useless spending for the military but they always say the government shouldnt cut military spending but food stamps and medicaid and etc.
