Himachal Pradesh has 68 seats and is governed by the Congress. Chief Minister Virbhadra Singh recently incited a revolt with most of the party's 36 legislators threatening to side with him if he is not given a free hand to run the party's campaign. Mr Singh, 83, is being investigated on corruption charges by the CBI; he has denied any wrongdoing. He has served six times as the small hill state's Chief Minister. After his threats, Congress Vice President Rahul Gandhi recently confirmed that Mr Singh is the party's presumptive Chief Minister.
Gujarat is also scheduled to go to polls later this year.
Congress leader Rahul Gandhi has spent this week campaigning in Gujarat too; he has called attention to the economic slowdown, the growing frustration over not enough jobs, and alleged that Mr Shah's son, Gujarat entrepreneur Jay Shah, has benefited from crony capitalism as a result of his father's influence.
