Somebody once said The President Proposes, Congress Disposes and the Supreme Court rules.
Add these facts about control of the House and Senate to that spending chart:
Years House / Years Senate was held by opposition party:
Gerald Ford 2/2...his entire term, the opposition party controlled both House and Senate
Jimmy Carter 0/0... his party ALWAYS controlled both the House and Senate
Ronald Reagan 8/2.. his party always had the House but the Senate only 2/8
Bush 1 4/4.. his entire term, the opposition party controlled both House and Senate
Clinton 6/6... for 3/4th's of his two terms, the Republicans controlled both House and Senate
Bush 2... 1/3... out of 7 years; he's had mostly Republican control in Congress
Now...
Gerald Ford, slight downward trend, mostly level with Congress under Democratic control.
Jimmy Carter, Ford's slight downward trend continues with Republicans totally controlling Congress but trend reverses to slightly up in last year.
Ronald Reagan, overall snapshot is that spending rises sharply with Republicans holding the House and the Democrats holding the Senate. So the Reagan spending was essentially approved by both parties.
Bush 1, spending skyrockets past the Reagan totals with Democrats controlling both houses of Congress for Bush 1's entire term.
Bill Clinton, overall steady downward trend in spending for both terms considering Bush 1's spending. Democrats control both houses of Congress for the first 2 years of Clinton's first term. Republicans took control of both houses of Congress for the last 6 years of the Clinton presidency. So 75% of those declining years the Congress was totally under Republican control.
Bush 2, spending again skyrockets with both Houses of Congress mostly under Republican control. However, a large part of this can be linked to the Iraq war which intially had the support of both parties. Even now, both parties generally are supporting the funding the war.
Just some things to consider that might not be apparent if one does not delve too deeply into the how and why of that chart.
