You don't agree because you apparently don't know the facts. You shouldn't rush to an opinion without them.
How about...
The Democrats in congress gave us huge deficits starting in 1970 all the way up until the GOP took over in 1994.
Starting that point the deficits got smaller every year until 2001 and the recession. The deficits then went up, but were on the way back down again.
Then the Democrats took over again and the deficit shot back up again!
FACTS:
Highest deficits passed by a GOP congress
3.5% in 2004
3.4% in 2003
2.5% in 2005
Highest deficits passed by a Democrat congress
10% 2009
8.9% 2010 But let's give them a pass on Obama...
Highest deficits passed by a Democrat congress with someone other than Obama in office
6% 1983 <- Reagan
5.1% 1985
5% 1986
4.7% 1992 <- Bush 41
4.2% 1976 <- Ford
3.9% 1993 <- Clinton
3,8% 2008 <- Bush 43
2.7% 1977, 78, 80 <- Carter
So in conclusion: Democrat congresses outspend GOP congresses no mater who is in the White House, with the sole exception of a few of Carter's years that were lower than Bush's two worst years.
Furthermore... in the last 40 years the deficit has exceeded 3% 17 times and only two of those were under GOP congresses.
But wait!!! There is more...
The only time in history that spending has gone down consistently was under a GOP congress.
From 1995 to 2001 spending dropped EVERY year. Seven straight years.
More!!
GOP controlled congresses have only spent more than 20% of GPD 3 times, Democrats... 23 times.
We could do this all day... in short the record of Democrats when it comes to spending and deficits SUCKS!
