It's the time in the political season to make way too much of the impact a vice president can have on the presidential contest.

So I hope you don't mind if I extend that amusing parlor sport into the arena of healthcare reform and consider how how Joe Biden's original proposal for healthcare reform compares to Barack Obama's.

If nothing else, it's a good way to parse a few of the issues likely to be magnified when Obama and McCain yammer back and forth about their healthcare plans in the coming weeks.

Biden's plan, unloosed on the public in October 2007 to support his presidential run, isn't that different from Obama's.

Both cover the usual list of Democrat healthcare touchpoints--making coverage affordable with subsidies to people and businesses, creating new public options to supplement private offerings, preventing insurers from denying coverage to the sick, emphasizing prevention and chronic disease treatment, etc., etc., etc., yada yada and so forth. 

Neither plan, significantly, follows the Hillary Clinton proposal for mandating coverage for all people. Neither does the vaporous plank on healthcare in the Democrat's party platform draft.

[Note: It's a bit tough to find information on Biden's plan at this point in history. The former presidential campaign website www.joebiden/home is now redirected to a page on Obama's site announcing Biden as VP, effectively airbrushing evidence of the Biden plan from the current debate. We can expect the same from mittromney.com any day now.] 

The key distinctions between the Obama and Biden proposals:

Mandates: Obama requires all kids to have insurance. Biden doesn't require anybody to be insured.

Uninsured: Like Obama, Biden would use a mix of subsidies, tax breaks and expanded  options to help people buy into either private or public plans not unlike the one enjoyed by federal employees. Unlike Obama, Biden would give adults 55-64 the option of buying into Medicare, again with subsidies as needed.

Insurance regulation: Obama would prohibit insurers from denying coverage based on pre-existing conditions. Biden would provide incentives to discourage insurers from doing so.

Drug prices: Obama favors changing laws to permit federal price negotiation with drug makers over the cost of drugs for Medicare, reimportation of drugs from other countries, and supporting development of generic drugs. Biden mentions only allowing bargaining for Medicare drug prices.

Health Tech: Both support investments in health information technology in order to make care stronger, safer and better looking. Obama wants to spend $10 billion over 5 years, then make use of certain tech mandatory. Biden wants to spend $1 billion per year.

Total estimated costs: Such estimates are fictional, of course, if not delusional. But Biden costed out his plan at $120 billion per year. Obama, that tightwad, estimates outlays of $60 to $65 million per year. Obama says he'll pay for it by rolling back Bush's tax cuts for people making over $250,000 per year. Biden didn't say how he'd pay the bill.
