After insisting he can’t support more than $1.5 trillion in new social spending, Sen. Joe Manchin asked his Democratic colleagues, “How much is enough?” But he should ask himself the same question.

Even if “paid for,” $1.5 trillion is still too much, after the $1.9 trillion in “COVID relief” spending that Democrats rammed through in March for a total of over $5.4 trillion in added outlays since the pandemic hit, not to mention the $1.1 trillion infrastructure plan that’s still waiting in the wings.

Oh, and will he go along with bogus “savings” to get the bill down by pretending new benefits will expire after just a few years?

Plus, the “pay for” to go with the $1.5 trillion proposal would still require hefty job-killing tax hikes that hurt poor and middle-class Americans the most, slamming the economy and cutting wages.

That’s why Manchin himself this summer was calling to hit “pause” on the entire effort to ram through all or part of the Bernie Sanders’ agenda this year.

Stick to those guns, senator.
