With all due respect how do we pay for this?

How do we pay for this especially in light of our deficit?  We don't even know the real costs of Obamacare and its full effect on the economy yet because so much of it has been deferred until the last two years of this President's time in office!

How do we reconstitute our military, fight an endless war in the Middle East, deal with infrastructure, absorb millions of new immigrants, deal with problems in the urban areas ....And pay for free community college?

I'm at a loss on this one.  Is this plausible or am I just too pessimistic?
