CARACAS, Dec 8 (Reuters) - Venezuelans voted in municipal elections on Sunday that are the biggest political test yet for President Nicolas Maduro as he tries to halt an economic slide and preserve the socialist legacy of his late mentor, Hugo Chavez.
The outcome of ballots to choose 337 mayors and around 2,500 councillors will be seen as a sign of Maduro's strength, nine months after Chavez died from cancer and he narrowly beat opposition leader Henrique Capriles to win the presidency.
'All patriots must vote so we can give a victory to our commander (Chavez) and guarantee peace and future for the fatherland,' Maduro, 51, said on Twitter in exhortation to supporters.
In Caracas shantytowns and elsewhere, pro-Maduro activists woke up supporters before dawn with bugle calls and trumpets in an election mobilization tactic begun under Chavez.
Opponents portray Maduro as a buffoonish autocrat with none of his predecessor's political savvy, and say his continuation of statist economic policies - including a new crackdown on businesses for alleged price-gouging - are disastrous.
'It's important to vote though I don't think it will bring the changes I want,' said graphic designer Antonella Gutierrez, 45, on her way to vote at a primary school in a pro-opposition upscale suburb of Caracas nestled under the Avila mountain.
'I want changes from the presidency down. This government is tearing the country into bits, destroying my Venezuela.'
Unlike the presidential votes that Maduro won in April and Chavez last year, morning queues appeared thin at poll stations. A healthy turnout of 60 percent or more was forecast however.
Though local issues such as roads, street lights and utility services were bound to affect individual mayoral races, both sides in the polarized OPEC nation also see the overall results as a crucial show of their standing at national level.
The ruling Socialist Party was likely to win a majority of municipalities thanks to its popularity in rural areas, where most of the mayorships are located, while the opposition wants to keep control of big cities such as Caracas and Maracaibo.
Both sides were desperate to win the total popular vote, though most pollsters predict that would again be broadly split down the middle, like the April presidential poll.
Investors are watching the ballot for indications as to whether Maduro will have the strength to push through unpopular economic measures, such as a currency devaluation that would help government finances but also spur inflation.
Should the opposition perform well, its leader Capriles has vowed to 'go for Maduro,' but not specified how.
The opposition's next opportunities to gain political ground are 2015 parliamentary elections and a signature drive for a recall referendum on Maduro in 2016. But some anti-government activists are pressing for more, like street protests.
Since taking office, Maduro, a burly 51-year-old former bus driver, has maintained core support among 'Chavistas' by keeping his popular welfare programs and repeating his rhetoric and politics. But Venezuela's economic problems have worsened.
Inflation has hit 54 percent, scarcities of basic products from flour to milk have spawned queues and annoyance around the country, power cuts are frequent, and the local bolivar currency has tanked against the dollar on the black market.
The economic problems had been weighing on Maduro's ratings, but his recent aggressive drive to inspect shops and businesses suspected of price-gouging - and arrests of several dozen retailers - has proved popular among core supporters.
One poll by local company Datanalisis, leaked by Wall Street analysts, showed Maduro had received a 10-point bounce from last month to 50.4 percent popularity just before Sunday's vote.
Maduro says U.S.-backed and opposition-linked businessmen are behind an 'economic war' intended to topple him.
In moves echoing Chavez's many clashes with the private sector, he has ordered companies to slash prices - delighting millions of consumers - and even sent troops to occupy a large electronics retailer he accused of price-gouging.
'He has made our Christmas a happy one. The government definitely has my vote on Sunday. Long live Maduro!' said Juan Alvarez, 31, a plumber queueing for newly cut-price shoes for his children at a Caracas sports shop this week.
One music video on state TV sings Maduro's praises in a play on the name Saint Nicholas, the model for Santa Claus: 'People of peace, lower your prices! Nicolas has arrived!'
Opponents, and some private economists, say the measures smack of short-term populism that do nothing to fix what they consider the roots of Venezuela's economic mess: persecution of the private sector, inefficiency and corruption in state businesses, an over-valued bolivar, and excessive controls.
'It is clear that, essentially, the idea is to stay in power, not the development of the country or people's welfare,' said Asdrubal Oliveros of local consultancy Ecoanalitica, which is often critical of the government.
As well as symbolizing the state of national politics, Sunday's election was also significant because mayors receive a sizeable portion of the country's oil revenue.
Spicing up the elections, the government has included several local celebrities on its mayoral roster, such as former baseball player-turned-rap singer Antonio 'El Potro' (The Colt) Alvarez who was fighting for a Caracas district.
Results were expected to start coming in on Sunday evening.
