I doubt anyone is surprised MoveOn answered Obama’s call to arms.

Dear MoveOn member,

This is it.

President Obama just proposed “the most aggressive and expansive national gun-control agenda in generations.”

Mandatory background checks for all gun buyers. A ban on assault weapons and high-capacity ammunition clips. More money for mental health. Stronger enforcement of the laws currently on the books.

It took a horrifying, unthinkable tragedy to put guns back on the agenda. But we finally have a real chance to put some sanity into America’s gun laws.

This won’t be easy. The NRA, backed by major funding from the gun industry, is already pouring money into a gutless TV ad campaign smearing President Obama as an “elitist hypocrite.”

But after President Obama’s big announcement, there’s no going back. We have to go big. We’re aiming to raise $200,000 today to beef up our grassroots campaign to pressure members of Congress and politicians at every level of government to get them on board with the president’s plan. Can you chip in $5?
