Opposition members accuse President Samia Suluhu Hassan of cracking down on dissent to stay in power.

Voters in Tanzania are heading to polling booths on Wednesday to vote for a new president, as well as members of parliament and councillors, in elections which are expected to continue the ruling Chama Cha Mapinduzi (CCM) – or Party of Revolution’s – 64-year-long grip on power.

Despite a bevy of candidates in the lineup, incumbent President Samia Suluhu Hassan, analysts say, is virtually unchallenged and will almost certainly win, following what rights groups say has been a heavy crackdown on popular opposition members, activists and journalists.

Key challengers Tundu Lissu of the largest opposition party, Chadema, and Luhaga Mpina of ACT-Wazalendo, have been barred from standing, thus eliminating any real threat to Hassan. Other presidential candidates on the ballot lack political backing and are unlikely to make much impact on voters, analysts say.

The East African nation is replete with rolling savannas and wildlife, making it a hotspot for safari tourism. It is also home to Africa’s tallest mountain, Mount Kilimanjaro, as well as a host of important landmarks, like the Ngorongoro Crater and the Serengeti. Precious minerals, such as the unique tanzanite – a blue gemstone – and gold, as well as agricultural exports, contribute significantly to foreign earnings.

Central Dodoma is the country’s capital, while the economic hub is coastal Dar-es-Salaam. Swahili is the lingua franca, while different local groups speak several other languages.

Here’s what to expect at the polls:
