FROM CNN's Jack Cafferty:

Money talks, and these days John McCain is getting an earful. And it's not good.

McCain raised $15.4 million in March. Barack Obama raised more than $41 million in March, and Hillary Clinton raised $20 million in March.

Overall, McCain has raised one third of the $240 million Obama has raised and less than half of Clinton's total. The Los Angeles Times reports that Obama has raised more in small donations than what McCain has raised in his entire campaign.

McCain's advisers and some Republicans insist he'll have enough money to run a competitive race in the general election, but not everyone is convinced.

One thing working in McCain's favor is the Republican National Committee, which is overwhelmingly outraising the Democratic National Committee.

The Republicans have about $31 million in the bank, compared to $5 million for the DNC.
