Don't hold your breath for anything. While it may be a first amendment right to petition the government for a redress of grievances, there is no such commitment for the President to do anything other than respond.
Although it met the 25000 signatures needed, the number remains somewhat underwhelming (imo) when compared to others. For example, on the 30th day the number was 26808, or 107.2% of the needed signatures. The petition to remove the Westboro Baptist Church's 503 (c) (3) status had 219.2% (more than twice the needed number) on day 30, the one to Remove United States District Attorney Carmen Ortiz had 210.1% on day 30, and the one to Endorse the National Rifle Association's "National School Shield" Program had 148.3% (1 1/2 times the needed number) on day 30.
Not trying to depress anyone, and I signed on day 2, but the reality is that I don't see us being as effective as other grass roots groups and I doubt we could reach the new petition threshold of 100,000.
Of course, if Barry is really a closet vaper, and directs a White House response rather than the last one that deflected the response through the FDA, then maybe it won't be a dead end street. But I'm not holding my breath.
If anything saves vaping from a ban, restrictions, or excessive costs, I'm guessing it will be successful lawsuits after the fact.
