PRAGUE, March 2 (Reuters) - A Czech transport strike set for Thursday has drawn the battle lines for a general election in May, giving the left a popular rallying call to protect welfare but casting the country's euro convergence programme into doubt.
Strikes are rare in this central European EU member, which has had a relatively good crisis with no bank failures and no loss of confidence requiring International Monetary Fund aid as occurred in Hungary, Romania and the Baltics.
But a sharp jump in the fiscal deficit, due mostly to a four percent economic contraction last year, has pushed euro entry back into the second half of the decade and made fixing the budget and protecting jobs the key issues in the May 28-29 poll.
Voters will also vent their frustration with politicians stained by a series of corruption scandals, which may bring new parties into parliament and complicate coalition building.
The election should break a deadlock that has gripped Czech politics since a centre-right cabinet that had limped along for two years without a parliamentary majority collapsed last year.
The leftist Social Democrats, led by former prime minister Jiri Paroubek, have a 5-13 percentage point opinion poll lead over the right-wing Civic Democrats, giving them the best chance of replacing the caretaker cabinet led by independent technocrat Jan Fischer. [
]But the polls do not guarantee them a solid majority that would allow for decisive policymaking.
The leftists have lured voters by pledging to raise benefits including pensions, and pay for it by taxing companies and high wage earners, and by finding efficiencies.
"We do not want to save on the people but on the operation of the state," Paroubek told Reuters on Monday.
They are backing the transport strike, called to support demands to restore tax breaks on employee benefits. The Civic Democrats, the Social Democrats' main rival, call the strike blackmail. [

FINE SO FAR, BUT CLOUDS BUILD UP
The leftists have at the same time pledged to stick to the current euro convergence programme, which provides for a drop in the budget deficit to 3 percent in 2013 from about 6.6 percent last year, making euro entry possible in 2015 or 2016.
Private sector analysts said the numbers do not add up, and taxing consumption rather than income would be a better idea.
"I do not believe they are now ready to stick to the convergence programme," said Ludek Niedermayer, a former central bank vice-governor, now at consultants Deloitte.
Neither of the big parties was ready for a thorough spending overhaul needed for long-term stability, he added.
Political analyst Jan Kubacek also predicts a slippage.
"They will say they are taking over in a more difficult situation than they had expected," he said.
"It (euro) will move back by a few years, which in itself is not fatal, because the euro zone is not ready to accept new members, perhaps with the exception of Estonia," he said.
However, market pressure for reforms will be big and whoever is in power will simply have to tighten up, Kubacek said.
The Czech Republic was among the first countries to start fiscal consolidation after the financial crisis, with tax hikes and moderate spending cuts this year, and it has a history of macroeconomic stability.
The caretaker government aims to cut the budget gap to 5.3 percent this year, and state debt will reach about 40 percent of GDP. That is low by European standards -- the euro zone average will be more than 80 percent of GDP this year -- but a sharp rise from 29 percent in two years, and the outlook is bleak with growing costs of debt servicing, healthcare and pensions.
The IMF said in January that without a credible plan "market sentiment could deteriorate and the cost of public sector borrowing increase".
CLEAR VICTORY ELUSIVE
Ales Michl, an analyst at Raiffeisenbank, said a clear win for either party would be the best scenario for the market.
"The best would be a big victory by either side, which would give a clear picture of what kind of policy will be done, rather than an unclear result muddying the picture," he said.
But polls suggest a messy outcome is more likely. The Social Democrats will need partners to form a coalition or, depending on the result, may opt for a minority cabinet with ad-hoc backing from other parties including the far-left Communists.
A close result would boost the chances of a grand coalition between the Social Democrats and the Civic Democrats. There is also a smaller chance of a centre-right coalition if a handful of small parties do well.
Newcomers such as the Conservative TOP09 and the little known liberal Public Affairs led by a former TV journalist have thrived on growing public frustration with seemingly omnipresent corruption in the political class, which is reported widely in the media but almost never leads to convictions.
Both major parties have been linked to suspicious deals but the Civic Democrats are more exposed due to scandals in their stronghold, Prague.
"If theft stopped, we would save 80-100 billion from public budgets. And I am being conservative here," Jaroslav Mil, head of the country's Industry and Transport Association and former head of the biggest central European company, the utility CEZ, said in a newspaper interview last week.
