WASHINGTON (AP) -- The government shutdown could last for many days or even weeks because politically safe members in both parties feel little pressure to compromise.
Heavily gerrymandered districts and other factors make many House Democrats and Republicans virtual shoo-ins for re-election. Congressional insiders say that helps insulate them from events and emotions beyond their home regions.
Most House Republicans insist that President Barack Obama curtail all or part of his landmark health care law.
But Democrats say it's absurd to yield ground on a major accomplishment that survived a Supreme Court challenge and Obama's 2012 re-election.
Both sides appear dug-in thanks to lawmakers' ideological beliefs and the strong support they generally receive from voters back home.
