A proponent of the Senate bill characterized the conservatives’ day of mobilization as a fizzle, contrasting it to crowded public demonstrations in support of the comprehensive reform.

“That wasn’t really a day of mobilization, that was just a lot of local grassroots groups that wanted to have press conferences. It wasn’t organized nationally,” said Beck.

The groups holding the press events delivered petitions circulated by NumbersUSA.

“Six years ago, seven years ago, the energy seemed to be on the other side, the other side was extremely organized. This time around the pro-immigrant people are very well organized,” said a Senate Democratic aide.
