Matt Yglesias thinks that the US Senate will stymie President Obama in any attempt to enact health care reform because -- well, because that's what the US Senate does:
The fact of the matter is that the Senate is what it is—to wit, an institution with an enormous status quo bias, that’s also biased in favor of conservative areas. On top of that, the entire structure of the US Congress with its bicameralism and multiple overlapping committees is biased toward making it easy for concentrated interests to block reform. Between them, Dianne Feinstein, Barbara Boxer, Chuck Schumer, Kristen Gillibrand, Bill Nelson, Dick Durbin, Roland Burris, Arlen Specter, Bob Casey, Sherrod Brown, Carl Levin, Amy Klobuchar, Kay Hagan, Bob Menendez, Frank Lautenberg, Mark Warner, Jim Webb, Patty Murray, Maria Cantwell, Ted Kennedy, John Kerry, and Evan Bayh represent 50 percent of the country’s population. But that only adds up to 22 Senators—you need thirty-eight more to pass a bill.
