If it’s Thursday, it must be another day of bipartisanship in Washington.

President Obama signed into law the JOBS Act at the White House — with House Majority Leader Eric Cantor (R-Va.) standing behind him. The two, who have been frequent nemeses over the past year, even shook hands after Obama finished putting his signature to paper in the Rose Garden.

It was the second day in a row that the president was hailing a newfound bipartisan spirit. On Wednesday, Obama signed the STOCK Act, which aims to curb insider trading by Congress and senior federal employees, with several Republican legislators in attendance.

The Jumpstart Our Business Startups law aims to eliminate barriers for entrepreneurs by allowing crowdfunding — which enables small businesses to solicit equity capital from investors over the Internet.

“For the first time, ordinary Americans will be able to go online and invest in entrepreneurs they believe in,” Obama said during the signing ceremony. “This bill represents exactly the kind of bipartisan action we should be taking to help economy.”

This show of unity comes after Obama flayed Republicans on Tuesday for failing to moderate their views, but it will probably be short-lived. Both sides want to show they can produce some legislative achievements — even during an election year.

But the GOP is still resisting larger pieces of Obama’s jobs agenda, such as his call for major investments in building roads and bridges, as well as more federal spending to help retain teachers, firefighters and police officers.

And even as Obama and Cantor shook hands, both sides were battling to take credit for the JOBS Act. In his remarks, Obama noted that he had called for measures included in the bill during his State of the Union address in January.

Not so fast, countered House Speaker John A. Boehner (R-Ohio).

“The JOBS Act – a key part of the Republican jobs plan – is good news for entrepreneurs and aspiring small businesspeople struggling to overcome government barriers to job creation,” Boehner said in a statement. “With so many Americans still asking ‘where are the jobs?,’ Republicans will continue to find and act on areas of common ground that would make it easier for small businesses to grow and hire new workers.”
