If we’re lucky, Thursday’s summit will turn out to have been the last act in the great health reform debate, the prologue to passage of an imperfect but nonetheless history-making bill. If so, the debate will have ended as it began: with Democrats offering moderate plans that draw heavily on past Republican ideas, and Republicans responding with slander and misdirection.

Nobody really expected anything different. But what was nonetheless revealing about the meeting was the fact that Republicans  who had weeks to prepare for this particular event, and have been campaigning against reform for a year  didn’t bother making a case that could withstand even minimal fact-checking.

It was obvious how things would go as soon as the first Republican speaker, Senator Lamar Alexander, delivered his remarks. He was presumably chosen because he’s folksy and likable and could make his party’s position sound reasonable. But right off the bat he delivered a whopper, asserting that under the Democratic plan, “for millions of Americans, premiums will go up.”

Wow. I guess you could say that he wasn’t technically lying, since the Congressional Budget Office analysis of the Senate Democrats’ plan does say that average payments for insurance would go up. But it also makes it clear that this would happen only because people would buy more and better coverage. The “price of a given amount of insurance coverage” would fall, not rise  and the actual cost to many Americans would fall sharply thanks to federal aid.
