Venezuelan opposition leader Henrique Capriles says President Nicolas Maduro's government will "cave in" under the pressure of growing economic troubles, in-fighting and a belief by many Venezuelans that it stole the April election.
Capriles is still disputing the election, which he lost to Maduro by a narrower-than-expected 1.5 percentage points. But if, as expected, the fraud claims get nowhere in Venezuela's courts, Capriles says other forces may sink the successor to the late socialist leader Hugo Chavez.
"I think this government, in the current conditions of illegitimacy added to a deep economic crisis it's showing no intention of addressing, is going to cave in," Capriles, the governor of Miranda state, told Reuters.
"What does that mean? Well, all the mechanisms are in the constitution: referendum, new election, resignation. But ... don't ask me for ways out that are not in the constitution. Our fight is a peaceful one," he added in an interview in a rural zone of the state on Friday.
Post-election street protests backfired for Capriles when some people were killed in the chaos, allowing the government to attack him as a destabilizer and killer.
Now he and other opposition leaders seem to be banking on a steady deterioration in Maduro's popularity and power. One possibility for opponents is a recall referendum, allowed in the constitution three years into a presidency.
That tactic was used unsuccessfully against Chavez during his 14-year rule of the South American OPEC nation.
Some opponents, though, say Venezuela's economic problems - slowing growth, untamed inflation, product shortages and hard currency bottlenecks - may prove too much for Maduro even before they can push for a recall referendum.
Capriles said a purported rivalry between Maduro and powerful Congress head Diosdado Cabello, also No. 2 of the ruling Socialist Party, was another factor to watch.
"They have an internal war ... and that person (Cabello) wants to be president but knows it's impossible via a popular vote. The only way, and this explains his game, is that things implode, break up, and he gets there by non-democratic means," said Capriles, 40.
Some opinion polls show Capriles a few points ahead of Maduro should a presidential election be repeated - an unlikely prospect, however, given the election board's multiple pronouncements that the results stand, including after an audit.
