Why don't Dems point out the # of jobs they've created when talking about the economy?

It’s the basic doom and gloom that is the bedrock of the Republican campaign for 2012 (presidential, local, congress, etc). They are pointing to the economy and saying Obama isn’t getting it done (probably because they know that the people are growing more and more in line with Dems/Libs on the other issues, but that’s another topic). Mitt Romney, the likely GOP presidential nominee at the moment even has a tagline “Obama isn’t working.”

Well if you look at the numbers, the US economy has added:
-1,253,000 Jobs from October of 2010 through May 2011 (every month showing positive growth)

-1,931,000 Jobs from November 2009 (the first positive month during the Obama administration) through May 2011, including 5 months total of job losses.

-And there was a steady decrease in jobs lost per month from the time Obama took office (January 2009) until we started adding jobs that fall.

That’s almost 2 million jobs added in the last 2 years. Why do they not point this out? People seem to think that we can gain back the 8 million jobs lost during the market crash overnight, and that’s simply not going to happen. We need responsible job growth, which is going to be steady. If you add 4 million jobs in a month, odds are most of them are not reliable and probably won’t last. Even the GOP demi-god Ronald Reagan added 8 million jobs during his entire presidency. It took REAGAN 8 years to build enough jobs to account for what Bush and company lost us in just a few short months.

Heck unless you discount all the jobs lost in the last months of Bushes presidency, Obama has made about 5 million more in the last 2 years than Bush did in his whole 8 (which all numbers combined would be about -3 million)

Why the hell aren’t they pointing this out? Just waiting for the Republicans to pick a candidate or something?
