The Democratic Congress that enacted President Barack Obama’s far-reaching health care law and plowed staggering sums into economic relief is at risk Tuesday in an election that promises to shake up the political order across the nation.

Republicans buoyantly forecast a new era of shared governance, two years after Democrats sealed victory in the presidency, the House and the Senate and set about reshaping the agenda in a time of severe recession and war. Democrats did not seriously dispute expectations that they would lose the House this time, even while campaigning through the final hours to stem losses.

The midterm elections are a prime-time test for that loosely knit and largely leaderless coalition, a force unheard of just two years ago. Tea party supporters rattled the Republican establishment in the primaries, booting out several veteran lawmakers and installing more than 70 candidates, nearly three dozen of whom are in competitive races Tuesday.

If successful, that conservative movement could come to Washington as a firewall against expansive federal spending, immigration liberalization and more, as well as a further threat to the historic health care law that Republicans hope somehow to roll back.
