Those who were waiting with bated breath for Tom Tancredo to light up will be disappointed. The former Republican congressman from Colorado, who promised to smoke weed—in public—if his state's marijuana legalization bill passed, has reneged on his pact. The conservative Republican was an unlikely supporter of Colorado's Amendment 64, which legalized weed for recreational use, but he says he never thought the bill would actually pass. "I thought it would take at least one more time around to do it," Tancredo told ABC News last week. In the newly released trailer for his film, Grassroots—The Comeback of Cannabis, comedian Adam Hartle asks Tancredo if he would agree to smoke a joint if the bill passed. “When marijuana legalization passes and marijuana is legal, the next time I’m out in Colorado, we’re going to smoke a joint together,” Hartle proposes. “Deal,” Tancredo replies, and they shake on it. Although on Friday, Tancredo vowed to keep the promise, he has now reportedly backed out of the deal due to pressure from his wife, who is "pissed" and his grandchildren who he says are "very upset with grandpa." "Will have to welch. Political heat is one thing. Am use to that," Tancredo wrote in an email. "Heat from my family is quite another."
