Washington, Aug 20 (IANS): Louisiana's Indian American governor Bobby Jindal, seen as a potential Republican presidential candidate in 2016, has an approval rating at 50 percent in his home state, according to an internal party poll.

Jindal, who was re-elected governor in 2011 for a second four year term, is term-limited that is he cannot contest for the State's top job again.

The poll found that 55 percent Louisianans support Jindal's controversial decision not to expand Medicaid, a US government health programme for families and individuals with low income and resources, with 37 percent opposed.

Four-fifths of Republicans also favour his Medicaid position.

The poll also found that 62 percent of Louisianans oppose Obama's signature healthcare law, nicknamed Obamacare, that aims to increase the quality and affordability of health insurance in US, 53 percent strongly so. Only 33 percent favour the law.

OnMessage Inc., Jindal's main consulting firm, surveyed 800 voters from Aug 12 to 15 for the National Republican Senatorial Committee, Politico reported.

The results were weighted to reflect historic turnout trends. The margin of error is plus or minus 3.5 percentage points.
