Larison tries to understand the significance of Brown's win:
[H]ow has Brown been able to rally opposition to the health care bill? By complaining that it would lead to Medicare cuts and interfere with Massachusetts’ system. In other words, he has based his candidacy around defending old entitlements against new ones. This is effective as a short-term tactic, as Brown has shown, but it should also tell the Democrats that establishing a new entitlement will be to their benefit as a matter of winning elections and popularity. In other words, Brown’s win actually proves that voters reward a candidate who voted for (statewide) universal health care and who is willing to defend it, which means that the electoral consequences of passing the federal bill should also be positive for the supporters of the bill.
