Budget deficit talks that broke down last week are now in the hands of President Obama and top senators â€” but remain mired in intransigence. At least three budget items arguably need to be on the table: revenue increases, entitlements and defense spending â€” but it's unclear any of them is. Minority Leader Mitch McConnell has declared "no new tax hikes." Two senators are introducing a Medicare savings bill that won't fly with Democrats, who win points by running against Rep. Paul Ryan's plan to "end Medicare as we know it." And defense cuts â€” even if small ones are achieved â€” are dicey for all.
