Pretty much the ultimate lefty insult.

(Reuters) — Demonstrators rallied at May Day events across the nation on Sunday, calling for reform on a host of issues and voicing frustration with President Barack Obama.

May Day events in New York, Chicago, Los Angeles, Boston, Milwaukee and Madison, Wisconsin were considerably smaller than in past years, as some of the hope for reform among Democrats that helped put Obama in the White House has faded.

Marchers in Chicago, where Obama cut his political teeth, expressed disappointment with aspects of his presidency, including his failure to close the U.S. military prison at Guantanamo Bay.

In New York, demonstrators called for immigration reform as well as support for environmental causes, tax reform and changes in U.S. defense policy.

Demonstrators carried signs reading “Legalization now, stop the deportations” and chanted “We are people, we are not illegal” as they marched down Broadway.

“Schools and hospitals are closing, jobs are being cut everywhere, and Wall Street guys are making money hand over fist,” said Ronny Williams of New York City.

“And then Washington’s spending billions on wars in places like Libya. Half the people I know are out of work,” he said.

Some carried signs pairing Obama with former President George Bush. “Obama you are not better than Bush,” read one sign.

Immigration reform was front and center in Chicago, where about 300 demonstrators gathered on the city’s west side before marching downtown.
