Most governments have been running deficits since forever, not since the last recession, after all, if there is economic grow, new money have to be created, and all money is originated in government spending.
But that's just a reality of how the economy works, that doesn't mean necessarily that Keynesian policies are followed (beyond the automatic stabilizers that are certainly Keynesian in design). Keynesian policies would be to try to offset a fall in aggregated demand by increasing fiscal spending, and that have been taboo since the 80's
