And so have a whole host of Republican leaders such as the chairman of the all-powerful House oversight committee, Darrell Issa, according to the Kashkari campaign.
Kashkari is a former US treasury department official who, as part of President Bush’s economic recovery team, designed the Troubled Asset Relief Program of 2008. Kashkari’s parents came to the US from India 50 years ago.
Kashkari has trailed in the polls badly and Los Angeles Times has called him "virtually unknown" with limited ability to raise funds. Kashkari is up against state assemblyman Tim Donnelly, a favourite of the Tea Party, a stridently conservative wing of the Republican party, who is raising prodigiously.
