Steve's barking at the last Keynesian Presidents

I gather that conservatives believe that Keynesian economics are those administration that used deficit spending to stimulate the economy.
That definition being true the last three presidents that used deficit spending are President Reagan. He cut taxes at the same time stimulated the economy by increasing the defense budget.
President Bush the second cut taxes at the same time encouraged the construction industry with cheap money for housing. ( I know that it's popular to blame the banks if your a liberal and Fanny and Freddy if your a conservative but I'll go with my gut) He also brought about a hole new agency Home Land Security with their hiring and buy equipment.
Now we come to President Obama, the first half of his administration was he was a Keynesian,the second part of his administration he's economic conservative ( any stimulus has to be paid for by cuts in other places).
To sum up that great modern conservative Ron Reagan was a Keynesian, so was President Bush the second were Keynesian. President Obama is only a lukewarm Keynesian.
