The KC-46A, like the KC-135, is a Boeing product.
We went back, created new criteria / changed it, and ensured Boeing got the contract worth >35 billion in 2011. Aren't we happy we did that? /sarc

You don't have competition anymore.
The competitors are broke / merged (example MD), and politicians (all of them on the take in some way) are making the decisions. So, you end up with stories like this.
I imagine had we gone with what an unbiased evaluative process decided is the best option, we would today already have a tanker: https://www.airforce-technology.com/projects/kc30tanker/ Based on the A330 which is a common air-frame (>1,600 built) and which has been around for a while ~ 30 years since it's first model appeared. This plane already existed in a tanker variant used by allies a year before it won the original bid (very low risk): https://en.wikipedia.org/wiki/Airbus_A330_MRTT
***But why opt for the cheap and low risk option, if you can take the high risk and more expensive option? / sarc
