(CNN) — In the wake of the country’s financial meltdown, Sens. Barack Obama and John McCain have been telling voters they’ll fix the economy while their opponent would only make it worse.

Sens. John McCain and Barack Obama are getting more specific about how they’d deal with U.S. economic woes.

As the economy dominated voters’ concerns, McCain and Obama stepped up the political blame game and got more specific about how they would deal with the country’s financial problems.
The candidates’ focus on the economy comes during a week of roller coaster activity in the financial markets:
There was the collapse of U.S. investment bank Lehman Brothers, a Bank of America buyout of Merrill Lynch and a government bailout of insurer AIG. Then, President Bush on Saturday asked Congress for the authority to spend up to $700 billion to purchase troubled mortgage assets and get things under control.

The Republican presidential candidate also wants to set up a Mortgage and Financial Institutions Trust, which he says would help companies avoid bankruptcy while protecting their customers. The money would also help consumers restructure loans so they can keep their homes.
"What’s missing on all of this? Well, the price tag," Foreman said.

Obama this week also also offered up a lot of proposals, including a commission similar to what McCain suggested.
The Democrat called for a Homeowner and Financial Support Act that would provide funds to prevent catastrophic failures in the financial industry and help keep people in their homes.
Foreman said this evokes the same question asked about McCain’s program: "What is this really going to cost? Who’s going to pay for it, and can we afford it?"
Obama also wants a $50 billion emergency economic stimulus plan. The money would go toward 1 million jobs for rebuilding infrastructure and schools, and helping local governments avoid budget cuts.
"This would obviously be targeted spendi
