WASHINGTON — “No” seems to be all anyone wants to say in this town anymore. In his State of the Union address on Tuesday, President Obama enumerated policies that he opposed, from rolling back Wall Street regulations to exempting more businesses from their obligation to provide health insurance under the Affordable Care Act.

To drive home his displeasure with the Republican agenda, the White House also issued two new veto threats in the hours before the president spoke — this time for bills that would ban abortions after 20 weeks of pregnancy and accelerate approval of natural gas pipeline construction.

For their part, Republicans immediately rejected most of the proposals that were central to Mr. Obama’s address, saying he was obviously not serious about working with them to pass consequential bipartisan legislation.

The midterm elections may have delivered more power to Republicans, who control Congress, but the tenor of the president’s address and the Republican response to it showed there was no new dawn of cooperation.
