Chicago ? Hispanic and other civil rights groups wrapped up plans for immigration reform marches and rallies today in dozens of cities, but conceded that a replay of last year’s huge turnout was unlikely.

Still, organizers said the demonstrations reflect a robust movement determined to win a path to citizenship for the estimated 12 million illegal immigrants in the country.

“There was a sort of energy last year,” said Gordon Mayer, a vice president of the Community Media Workshop, which helped groups organize the Chicago march. “This year that boulder has split up into a lot of smaller rocks.”

Marches, meetings and voter registration drives were planned from Oregon to Florida.

Last year’s May 1 boycott brought out more than a million protesters across the nation. But later rallies failed to produce large turnouts, as legislation stalled in Congress and bipartisan proposals for illegal immigrants to gain citizenship have become more conservative.
