One of George W. Bush’s biggest giveaways to massive corporations was his Medicare Part D plan. Part D specifically prohibited Medicare from negotiating for lower drug prices. Even worse, it featured the infamous “doughnut hole,” under which every plan included a massive gap in coverage.

Thankfully, Obamacare will phase out the doughnut hole by 2020, and it’s already starting to improve coverage for seniors:

The “doughnut hole,” an anxiety-inducing catch in an otherwise popular benefit, will shrink about 40 percent for those unlucky enough to land in it, according to new Medicare figures provided in response to a request from The Associated Press.

The average beneficiary who falls into the coverage gap would have spent $1,504 this year on prescriptions. But thanks to discounts and other provisions in President Barack Obama’s health care overhaul law, that cost fell to $901, according to Medicare’s Office of the Actuary, which handles economic estimates. [AP, via Political Animal]

As a reminder, the Republican Party wants to repeal Obamacare. In fact, they have frequently pledged to repeal it. At the same time, they have proposed ending Medicare. And they want seniors to vote for them in 2012?
