The Burden of Pelosi

In May 2008, Nancy Pelosi, the Democratic House Speaker, sponsored this bill: http://www.govtrack.us/congress/bill.xpd?bill=h110-3221
which forced tax payers to insure up to $300 billion of refinanced loans for "distressed borrowers".

In January 2008, Pelosi sponsored this bill: http://www.govtrack.us/congress/bill.xpd?bill=h110-5140&tab=summary
which imposed additional regulations on Fannie Mae and Freddie Mac.

Then today, Pelosi said this shortly before the vote on the bailout act:
“Madam speaker, when was the last time anyone ever asked you for $700 billion? It’s a staggering figure. ... But only a part of the cost of the failed Bush economic policies to our country. Policies that were built on budget recklessness. ... And now eight years later, the foundation of that fiscal irresponsibility, combined with an anything goes economic policy, has taken us to where we are today.... No regulation, no supervision, no discipline."

And after it didn't pass she said:
"We must work in a bipartisan way in order to have another bite at the apple in terms of some legislation,"

Is this lady a burden on our economy or not?
