Usually media bias in straight news stories is a rather subtle affair. This example, from The New York Times Monday paper isn't so subtle. (via Timeswatch)

The Republican plan includes a shrinking of Medicare and Medicaid and trillions of dollars in tax cuts, while sparing defense spending. Mr. Obama, by contrast, envisions a more comprehensive plan that would include tax increases for the richest taxpayers, cuts to military spending, savings in Medicare and Medicaid, and unspecified changes to Social Security.

The unbiased way to present this information is to say that both parties would "cut" (or "slow the growth" since that's what a cut in Washington, D.C. is) Medicare and Medicaid. The most troubling thing about this sort of bias is that they really don't know they're doing it.
