If you want the White House to respond to your queries or take action, you're petition is going to need more signatures. On Tuesday, it announced that the number of signatures required to illicit a response had been raised to 100,000—four times the previous requirement.
New media director Macon Phillips says the decision was motivated by the success of the White House's "We the People" website:
In the first 10 months of 2012, it took an average of 18 days for a new petition to cross the 25,000-signature threshold. In the last two months of the year, that average time was cut in half to just 9 days, and most petitions that crossed the threshold collected 25,000 signatures within five days of their creation. More than 60 percent of the petitions to cross threshold in all of 2012 did so in the last two months of the year.
The bulk of the petitions that met the threshold were secession petitions, which were all dismissed with the wave of a magic wand. More than anything, the White House wants to make it more challenging for people to draft petitions for absurd causes that they actually have to respond to.
